12:15 : Ultrathin q-wave plates based on double-L shape plasmonic nanoantennasAli Kabiri, Emad Girgis, Federico Capasso

Double-L resonators are designed to achieve a strong anisotropic optical response. An ultrathin quarter wave plate formid-infrared frequencies is demonstrated based on array of double-L shape plasmonic nanoantennas. Experimentalresults are in a good agreement with numerical simulations. The proposed design shows a relatively wide bandwidthresponse which is suitable for many applications.

12:35 : Microwave propagation in nonlinear MTMS film surround by anisotropic materialsHala Jarallah El-Khozondar, Rifa Jarallah El-Khozondar, Said Zouhdi

In this work, we studied the characteristics of waveguide consists of nonlinear MTMs surrounded by anisotropic mate-rials. The dispersion equation is derived from Maxwell’s equations. We considered only TE modes in the microwaverange. Results display the different behavior of the propagating waves as the refractive index of refraction of MTMschange and as the thickness of the film changes.

12:55 : Tunable left-handed metamaterial based on ferriteJavad Ghalibafan, Nader Komjani, Behzad Rejaei

This paper proposes, a tunable left handed (LH) transmission line consisting of a transversely magnetized ferrite rectan-gular waveguide loaded by complementary split-ring resonator (CSRR). The left handed behavior is realized by combin-ing the negative permittivity of the CSRR with the negative permeability of the transversely magnetized ferrite, despitethem being spatially separated. It is shown that, the left-handed frequency band of this structure can be tuned by changingthe DC bias magnetic field applied to the ferrite.

We report Raman scattering of ferroelectric BaTiO3 (BT) film and superlattice (SL) consisting of BT and paraelectricBaZrO3 (BZ). These nano-structures have been growth by a pulsed laser deposition. The epitaxial BT film and BT andBZ layers with a periodicity of 256Å were deposited on MgO substrate buffered with LSCO layer. The spectra revealedthat the strain reduces Ti4+ ions disorder and suggest a monoclinic phase in BT layers and polar phase in BZ layers forthe SL.

12:15 : Invited talkAn overview of sum rules and physical limitations for passive metamaterial structuresMats Gustafsson

Metamaterials offer many new possibilities to design structures and devices with improved performance. In this paper,we present an overview of physical limitations for passive structures. We present results for extinction cross sections,radar absorbers, high-impedance surfaces, extraordinary transmission, antennas, and temporal dispersion of metamate-rials. The results provide a tradeoff between possible performance and bandwidth. As they are derived solely usingpassivity and linearity, the results also state when it is necessary to use active or non-linear media.

12:35 : Invited talkA sparse scattering model for nanoparticles on rough substratesMirza Karamehmedovic, Poul-Erik Hansen, Thomas Wriedt

We present and validate an efficient forward scattering model for nanoparticles on rough contaminated substrates.

12:55 : Invited talkGold nanoparticle doped polymer materials for micro- and nanofabricationSøren Vang Fischer, Noriyuki Masuda, Stephan Sylvest Keller, Basil Uthuppu, Mogens Havsteen Jakobsen

Gold nanoparticle SU-8 composite was structured by UV photolithography. Point-wise light scattering was observedthrough dark field microscopy. Plasmonic extinction peaked at 550 nm and similar response was observed by briefMie calculation at n=1.63. Spherical gold nanoparticle possesses isotropic feature. However, the composite showedpolarization dependency to incident light, indicating that the particles were self-organized chemically and/or physicallyduring the fabrication.

Chaired by: Arkadi Chipouline

12:15 : Theory and simulation of cavity quantum electro-dynamics in multi-partite quantum complex systemsMoslem Alidoosty Shahraki, Sina Khorasani

The general behavior in cavity quantum electrodynamics of complex systems is analyzed. Such quantum optic multi-partite systems normally consist of an arbitrary number of quantum dots in interaction with an arbitrary number of cavitymodes. For the first time, we observed a chaotic behavior in the ultrastrong coupling regime. Results are presented and

8


discussed for the behavior of a real quantum optic system and a multi-partite system consisting of six quantum dots ininteraction with one cavity mode.

12:35 : Angular dependence of the optical response of a magnetic anisotropic material: analytical/numericalanalysisMarc Warenghem, Jean François Blach , Jean François Henninot, Salim Nemer

We propose a 3 steps method to analyze the role of anisotropy (dielectric and magnetic). The two first consists in findinganalytical expressions for propagation elements and their link with measurable quantities. The third step consists incomparing those results, which involve constitutive relationships, to results which do not involve any effective opticalparameters. In this communication, we focus on the first two steps to lay the foundation for this approach.

12:55 : The investigation of the photonic waveguide structure made of silicon carbide by means of the method ofthe singular integral equationsT. Gric, L. Nickelson, R. Martavicius

Here we present the investigation of the photonic waveguide structure by means of the method of the Singular IntegralEquations. We discovered peculiarities of the dispersion characteristics.

12:15 : Transformation electromagnetics for efficient solution of rough surface scattering problems by finite meth-odsOzlem Ozgun, Mustafa Kuzuoglu

A computational model is presented by combining the principles of transformation electromagnetics and finite methods(such as finite element method or finite difference methods) for efficient Monte Carlo simulation of rough surface scat-tering problems. A simple, single and uniform mesh is employed through repeated Monte Carlo realizations. Hence, thecomputation time is reduced to a great extent. The technique is demonstrated via various finite element simulations.

12:35 : Invited talkFocusing properties of the Maxwell fish eye lensRhiannon Christine Mitchell-Thomas, Oscar Quevedo-Teruel, Yang Hao

This summary outlines the origin and design of the Maxwell fish eye lens as a sub-wavelength image system, and itsassociation with non-Euclidean transformations. A brief discussion of the focusing property is given, which is supportedby two simulation techniques: 1) ray tracing illustrating the focusing in the limit of geometrical optics, and 2) a finiteelement method simulation, showing that the focusing property is retained for wave optics.

12:55 : Invited talkExperiments on transformation thermodynamics: Molding the flow of heatRobert Schittny, Muamer Kadic, Sebastien Guenneau, Martin Wegener

It has recently been shown theoretically that the time-dependent heat conduction equation is form-invariant under curvi-linear coordinate transformations. Thus, the concepts of transformation electrodynamics can be applied to thermody-namics as well. Following these ideas, we design, fabricate and characterize a thermal cloaking device that molds theflow of heat around an object in a metal plate. The object is protected from heating while the downstream heat flow ispreserved as if no object was there.

14:30 : Invited talkA Robustness analysis of the numerical computation of green’s dyadics in bianisotropic mediaIgnace Bogaert

The robustness of a previously developed numerical algorithm for the computation of the four Green’s dyadics in ho-mogeneous bianisotropic materials is analyzed. The lossy bianisotropic materials are identified as a class of materialsfor which the numerical computation is provably robust. This is of practical importance because many bianisotropicmaterials are lossy.

14:50 : Invited talkSelective mode suppression in microstrip differential lines by means of electric-LC (ELC) and magnetic-LC (M-LC) resonatorsJordi Naqui, Miguel Duran-Sindreu, Ferran Martin

In this paper, it is demonstrated that the so-called electric-LC (ELC) resonators, and their dual counterparts, the magnetic-LC (MLC) resonators, are useful for the selective suppression of either the differential or the common mode in microstripdifferential lines. The key point to mode suppression is the alignment of the electric (differential mode) or magnetic(common mode) walls of the line with the resonator.

15:10 : Invited talkEnhanced circuit modeling of metasurfacesFrancisco Mesa, Raul Rodriguez-Berral, Francisco Medina, Maria Garcia-Vigueras

This paper presents some recent advances in the circuit modeling of 1-D and 2-D periodic metasurfaces. Most ofthese advances are focused in the obtaining of a fully-analytical equivalent circuit model for the scattering of anobliquely-incident plane wave on a metasurface composed of a periodically patterned metallic surface embedded ina layered dielectric environment. Our approach also provides the “exact” topology of the network that models thereflection/transmission effects of the metasurface.

15:30 : Invited talkAnalysis of penrose photonic quasicrystals via Bloch’s theorem in 5-dimensional superspaceFarhad A. Namin, Douglas Werner

The lack of translational symmetry presents a major challenge in evaluating the properties of photonic quasicrystals.Previous studies have largely relied on approximate truncated supercell models. We propose an exact solution to capturethe entire infinite structure. We exploit the fact that quasicrystals can be obtained as irrational projections of higherdimensional periodic lattices. This property allows us to solve the field equations in higher dimensions where Bloch’stheorem applies and then project the solution onto the physical space.

Biosensing technologies that can study biological systems and their dynamic interactions are important for understandingof fundamental biological process and our ability to diagnose and treat diseases.

Kasture, Y.V. Jayasurya, AchantaGopal , Alexander Grishin, S.I. Khartsev, L.L. Doskolovich, D.R. Yakovlev, A.K. Zvezdin, M. Bayer

Here we postulate a novel magneto-optical phenomenon which originates solely from suitably designed nanostructuredmetal-dielectric material, so called magnetoplasmonic crystal. For the considered configuration the effect cannot occurin smooth samples. The effect shows up as a change of the optical transmission/reflection when the sample is magnetizedin-plane.

14:50 : Deep subwavelength double metal disk cavity and applicationsSoon-Hong Kwon

We propose a deep subwavelength plasmonic double metal disk cavity. By reducing radius and thickness carefully, thesurface-plasmon-polariton cavity mode with a resonant wavelength of 1550 nm can be confined in a disk with a radiusof 88 nm and a thickness of 10 nm, where the physical size is 0.000064 l3 (l: free space wavelength). The cavity modehas a deep subwavelength mode volume of 0.010 (l/2n)3 with high Q of 1900.

15:10 : Coupled nano-plasmonsMarian Apostol, Stelian Ilie, Aurel Petrut, Marcel Savu, Stefan Toba

A simple model of coupled plasmons arising in two neighbouring nano-particles is presented. It is shown that theplasmons may be periodically trasferred between the two particles. For larger separation distances between the twoparticles the retardation is included. The van der Waals-London-Casimir force is estimated for the two particles, it isshown that for large distances the force is repulsive.

15:30 : Surface plasmon and bound plasmon-waveguide resonances with As2S3 light sensitive films in four layersconfigurationAurelian Popescu, Dan Savastru, Sorin Miclos, Simona Dontu

The surface plasmon resonance calculations were made in Kretschmann configuration that contains four layer. Thethird layer consists of a thin As2S3 vitreous film. The sensitivity to the refractive index was calculated. The picksharpness analyses of plasmonic resonance and bounded plasmon-planar waveguide resonance give the road to improvethe sensibility to the refractive index changes in four layer plasmonic structure.

15:50 : Strong emission from nano-iron using laser induced breakdown spectroscopy techniqueFareed Faris Rashid, Ashraf El-sherbini El-sherbini, Abdulsalam Al-Muhammady

We report a strong emission from laser produced plasma from iron oxide nanomaterials. Analysis showed such enhance-ment increased with the plasma evolution time, while, it declines as the laser fluence increased. The enhancement differswith different laser harmonics. Experimental analysis showed that enhancement is mainly associated with change in theelectron density. We claim that strong enhanced emission is due to surface plasmon resonant excitation. Such resultscould improve LIBS-sensitivity to detect materials at very low concentrations.

16:10 : Four Vertical Prolate Spheroids with a Center Gap as NanoantennaMahdieh Khosravi, Ramezan Ali Sadeghzadeh, Mohammad Sadegh Abrishamian

In this paper, we first investigate the properties of a single prolate nanospheroid of different materials to determine basicelement. Next, we study the behavior of a structure of four vertical prolate spheroids of same dimension with a centergap (g). Finally, simulation results for different parameters variation (element size and gap distance) have been presentedby order. As a result, this semi-turnstile nanoantenna produces intense optical field enhancement when illuminated atthe resonant wavelength.

Active planar structures enabling stimulated emission or amplification of surface plasmon-polaritons (SPPs) are of strongcurrent interest, as are structures for their detection. Both types of active structures are discussed.

15:10 : Invited talkAccurate finite difference analysis of novel trenched channel plasmonic waveguidesAhmed Mahmoud Heikal, Mohamed Farhat Hameed, Salah Sabry Obayya

Accurate modal analysis of a novel design of three trenched single mode channel plasmon polariton is introduced andanalyzed. The simulation results are obtained using accurate full-vectorial finite difference method for linear obliqueand curved interface which overcomes staircase problem of the conventional finite difference methods. The suggesteddesign has a good confinement behavior similar to the V-grove structure with improved propagation length. However,the reported structure is easier in fabrication and design with lower propagation loss.

15:30 : Novel symmetric mixed finite element analysis for hybrid dielectric-loaded plasmonic waveguide struc-turesShymaa Ibrahim Hassan Ibrahim, Salah Sabry Obayya

A modified symmetric mixed finite element is introduced to be utilized in the modeling of metal-based nanophotonicstructures, namely nanoplasmonic waveguides. Besides the benefits of conventional curl conforming mixed elements, thesymmetric element has the advantage of being independent on the selection of facet related basis functions. Numericalresults show the effectiveness of the proposed symmetric elements in simulating plasmonic structures.

15:50 : Invited talkOptical Hyperspace: light propagation and related phenomena in metamaterials with hyperbolic dispersionEvgueni Narimanov

Metamaterials with hyperbolic dispersion (where two eigenvalues of the dielectric permittivity tensor have oppositesigns) exhibit a broad bandwidth singularity in the photonic density of states, with resulting manifestations in a varietyof phenomena, from spontaneous emission to light propagation and scattering. In this presentation, I will review someof the recent developments in this field.

14:30 : Invited talkPolarization-independent Fano resonance in oligomer structuresBen Hopkins, Wei Liu, Andrey E. Miroshnichenko

We study the optical responses of plasmonic and all-dielectric oligomers structures that have an n-fold symmetry. Un-der certain conditions oligomer structures may support well-pronounced Fano resonance. In the limit of the discrete-dipole approximation we analytically prove that all the cross-sections are independent of the angle of polarization ofthe linearly-polarized plane wave. However, the near-field distribution does depend on the incident polarization. Suchpolarization independence reveals the peculiar origin of the Fano resonance in oligomer-like structures.

14:50 : Invited talkMultiple-source excitation of active coated nano-particlesSamel Arslanagic

The present work investigates the resonance and transparency effects that occur in electrically small active coated nano-particles in the case of multiple-dipole excitation. While the resonance effects are found for dipole locations both inside,as well as outside, the nano-particles, the transparency is only in evidence for dipole locations exterior to particles.Furthermore, the work reports on interesting pattern-rotation possibilities when several dipoles, of different orientationsand locations, excite a super-resonant active coated nano-particle.

15:10 : Invited talkA cloak from self-assembled metallic nanoparticlesCarsten Rockstuhl, Stefan Mühlig, Mohamed Farhat, Shakeeb Bin Hasan, Alastair Cunningham, Thomas Bürgi, JoseDintinger, Toralf Scharf, Falk Lederer

We present the theory, the realization, and the successful experimental characterization of a cloak that was fabricatedusing self-assembling techniques from the field of colloidal nanochemistry. The cloak essentially consists of plasmonicnanoparticles that decorate the object to be cloaked, which is a dielectric sphere. It is shown that the cloak almostperfectly suppresses the scattering response of the dielectric sphere in the electric dipolar limit. Extensions to cloakmore macroscopic objects are additionally discussed.

15:30 : Enhanced optical absorption of nanoparticles in multiple scattering regimeJean-Paul Hugonin, Mondher Besbes, Mathieu Langlais, Philippe Ben-Abdallah

Using the coupled multipoles theory and a finite element solver of Maxwell equations we compute the apparent absorp-tion of nanoparticles in two-dimensional nanoparticles lattices immersed inside semi-infinite transparent materials. Formetallic nanoparticles we demonstrate that this absorption can be enhanced in the visible range by more than one orderof magnitude compared with isolated particles thanks to multiple interactions with the neighbourhoods particles. Thesemultiple interaction mechanisms pave the way to a new strategy for engineering light absorption.

15:50 : Invited talkPlasmonic nanoparticles as dielectric tuner, sub-wavelength light confiner and heat generatorMady Elbahri

Plasmonic nanoparticles drawn the attention in the last few decades due to their exotic properties ranging from sub-wavelength optics up to guiding of the light and heat generation. In this work, the great potential of nanoparticles as arefractive index tuner, light trapper and heat generator will be thoroughly discussed.

16:10 : Invited talkNanometric gaps in plasmonics nanostructures: Mode visualization, the classical limit, and transformation opticstreatmentStefan Maier

Recent progress in nanofabrication has enabled the generation of metallic nanoantennas with gaps on the order of onlya few nanometers. Even structures such as the simple bow tie can sustain a number of bright and dark plasmon modes,revealed via electron energy loss spectroscopy. We further discuss the limits of the classical electromagnetism frameworkon this length scale.

Here, we report on the analytical modeling and physical properties of conformal metasurface cloaks excited by an electricline source. The realistic metasurface cloaks are formed with 2-D periodic arrays of printed (patches or Jerusalemcrosses) and slotted (meshes or Jerusalem cross slots) sub-wavelength elements. It is demonstrated that the analyticalgrid-impedance expressions, originally derived for planar metasurfaces and plane-wave incidence, may be successfullyapplied in the analysis of cylindrical conformal mantle cloaks illuminated by near-field sources.

Active metamaterial devices consisted of double layer complementary split ring resonators (CSRRs) were studied. Theywere fabricated by ion beam etching method on Au-SiO2-Au films, and the biased voltage can be applied on the topand bottom electrodes of the device. Light amplification was observed in transmission spectra for different incidentpolarizations.

The possibility of selectively cloaking 3D objects at Terahertz frequencies is demonstrated. The cloak design relies ongraphene layers enfolding dielectric shells and biased via an external electric field. Particularly, two configurations areinvestigated: (i) Only one layer of graphene is used to suppress the scattering from a dielectric sphere. (ii) A stack ofthese layers biased at different gate voltages are used to realize multi-frequency cloaking.

We describe an all-angle negative refraction effect for surface acoustic waves (SAW) in 2D phononic crystals madeof cylindrical pillars assembled in a square lattice and deposited on the surface of a semi-infinite substrate. The iso-frequency contours convexity of some branches leads to a NR effect. A flat lens for SAW has been designed demonstrat-ing the focusing of an acoustic source into an image on the other side with an image resolution of l/4, which overcomesthe diffraction limit.

Electromagnetic wave propagation in metamaterials including photonic crystals has been widely investigated due totheir inherent capabilities for developing novel devices in optics, microwave and antenna engineering. In reality, mostof the materials are frequency-dependent, on the other hand, it is necessary to investigate how the performance ofphotonic crystals depends on frequency. In this paper, it is shown that the eigenmodes can be accurately calculated intwo-dimensional Lorentz-type frequency-dependent photonic crystals using a new finite-difference frequency-domain(FDFD) algorithm.

A long-standing issue in plasmonics is that surface plasmonic polaritons (SPPs) are subject to large scattering losswhen encountering a sharp corner or an obstacle. We address this problem by adopting the method of nonmagnetictransformation optics. Layered dielectrics can be used to efficiently guide SPPs through a right-angle, zero-radiusbending corner, or guide SPPs to circumvent a bump on a flat surface as if the bump was not there. We experimentallytested the above strategies in microwave regime.

11:20 : Invited talkPhoton management in two-dimensional disordered mediaMatteo Burresi, Kevin Vynck, Diederik Wiersma

We present a novel nanophotonic strategy based on disorder to greatly augment the absorption of thin-film materialsover a large range of wavelengths. The introduction of a properly engineered 2D random structure in thin-slabs givesrise to guided disordered modes, which traps light impinging from the third direction, thus enhancing the absorption.Furthermore, by properly introducing correlations in the random structure we are able to control spectrally and angularlythe coupling properties of the photonic disordered structure.

11:40 : Negative refraction, perfect lenses and new objectives in metaatom researchManuel Nieto Vesperinas

The proposal of negative refractive index media and their use for imaging superresolution was precluded by their inherenthighly lossy transmittance. Recently a new road is aimed by employing their magnetic response to illuminating wavesand their high absorption of incident energy. While the former property conveys effects like Fano resonances, Kerker-like suppression of scattered intensities in given directions, or highly directional scattering, the latter characteristics leadto new concepts for storage and emission of electromagnetic energy.

We analyze the light scattering by a magnetodielectric subwavelength isolated sphere and its capacity to show non-usual scattering properties, like the inhibition of backward scattered intensity and the almost inhibition of the scatteredintensity in the forward direction. The possible relevance of this study in micro and nano- technological fields will bepresented.

The availability of local, homogeneous metamaterials is of utmost importance for most devices that rely on metamate-rials. The desired locality of the response, however, is usually not proven or actually even not questioned. Here, wepresent a promising set of meta-atoms that provide the desired local artificial magnetic response by exploiting the ex-tremely strong coupling regime. We discuss their properties, possibilities, and limitations comprehensively in terms of amultipole expansion technique.

We show that thefundamental Bloch mode approximation is of paramount importance, since it provides probably the only way to deriveunique effective parameters. The physical origin of common issues like the convergence of effective parameters with thethickness of the sample is resolved within this contribution.

We study the optical performance of organic light emitting diodes (OLEDs) with the corrugated cathode. We modelthe outcoupling efficiency of OLEDs with two-dimensional periodic as well as random corrugations of the cathode. Weshow that outcoupling efficiency of vertically oriented emitters is greatly enhanced by the presence of corrugations, inaccordance with experimental findings. The enhancement is strongly dependent on both geometry of corrugations andmaterial parameters of the cathode.

From direct electric excitations on SRR structures, we demonstrated multi-mode plasmonic resonances that can bequantitatively described by our standing-wave plasmonic resonance model. We further manifest that the lower-ordermodes possess greater sensitivity associated with stronger localized electromagnetic field leading to greater sensitivity,while the higher-order modes present mediate sensitivity with micron-scale detection lengths to allow intracellular bio-events detection. These unique merits enable the SRR-based sensor a label-free, coupler-free, scalable and intracellularsensing/imaging device.

The polystyrene (PS) HS and NC array have a graded index profile, resulting inbroadband antireflection. Additionally, they can enhance light trapping by whispering gallery mode (WGM) resonancesexcited in the hemispherical or conical structure. FDTD simulation results show a confinement of incident light insidethe HS or NC structure and resulting sharp resonance peaks verify the WGM resonance.

We show that thereis an optical frequency range in which the scattering asymmetry parameter is negative and hence the dispersion acquiresa transport mean free path smaller than its scattering mean free path. The effective refractive index and reflection andtransmission coefficients of a disordered thin film will be discussed.

By placinga point-like dipolesource near a single dielectric particle driven at the magneticresonance results the radiation patternsimilar to that of a Huygenssource with the enhanced forward and vanishing backward emission.This feature can beemployed in the Yagi-Uda geometry for highly efficient optical nanoantennas.

14:30 : Invited talkFull-vector analysis of photonic gain/loss structuresJiri Ctyroky

Photonic waveguide structures with a balance of gain and loss have been mostly analyzed either in a 2D approximation,or by using of the coupled mode theory in which the vectorial character of modal fields is not considered. Here wepresent results of a vector analysis of gain/loss waveguide structures and show that the existence of a critical gain/lossvalue, at which the behaviour of the structures is dramatically changed, is retained at least for some modes.

15:10 : Invited talkSurface plasmon components for parity-time symmetric systemsPierre Berini

Passive and active long-range surface plasmon waveguide components are of interest for the implementation of parity-time (PT) symmetric systems. We review recent work on passive integrated elements such as straight waveguides,bends, couplers and Bragg gratings, and on the prospects of incorporating gain in such elements in order to achieve PTsymmetric systems.

15:30 : Invited talkGuided-wave devices with fixed losses inspired by PT-symmetry and their spectrum singularityHenri Benisty, Anatole Lupu, Aloyse Degiron

Guided-wave devices with plasmonic-type fixed losses can be adapted to exploit the singular point behavior well knownfor exact PT symmetric guides. Coupled guides having fixed losses and variable gain fail to exhibit a singular point intheir eigenvalues if the guides’ effective indices coincide. We show how to heal this situation and restore singularityby detuning among the guides. We also present a frame inspired by Kogelnik’s representations of alternate Delta-Betacouplers to usefully account for several configurations.

15:50 : Invited talkExploring effective PT-symmetric Hamiltonians using metamaterialsMing Kang, Fu Liu, Jensen Li

We theoretically investigate the analog of PT-symmetric non-Hermitian quantum mechanical systems using metamate-rials, which can provide a flexible testing ground for PT-symmetry. We show that spontaneous PT-symmetry breakingcan be achieved by exploring the interplay between the near-field coupling and material absorption or gain. An idealPT-symmetry can also be established effectively in a passive system. Coherent perfect absorption and amplification aredemonstrated as examples.

54


We proove existence of discrete solitons in parity-time (PT-) symmetric lattices, which describe stationary light propaga-tion in networks of waveguides with dissipation and gain. The energy balance between dissipation and gain implies thatin the anticontinuum limit the solitons are constructed from elementary PT-symmetric blocks such as dimers, quadrimers,etc. We consider in detail a chain of dimers, analyze bifurcations of discrete solitons and show that the solitons are stable.The approach is illustrated on examples of networks of quadrimers.

Pentamode metamaterials are artificial structures which - despite being solids - approximately resemble the mechanicalproperties of a liquid, having a finite bulk but vanishing shear modulus. Anisotropic versions of these structures are apromising candidate for applications in transformation-elastodynamics. We theoretically discuss possibilities for intro-ducing anisotropy into three-dimensional pentamode structures and show examples of corresponding fabricated macro-as well as microstructures.

In this work, we have introduced a comprehensive study of the stop-band/pass-band dispersive behavior of 1D phononiccrystals. We have treated the propagation and localization of elastic (in-plane) waves incident normally to perfect binaryphononic crystals. Based on the transfer matrix method and Bloch theory, the reflection coefficients are calculated andplotted for the in-plane waves. We have studied the effect of temperature on the phononic band gaps for the in-planewaves. These results can be useful in using phononic crystals as temperature sensor materials.

This paper examines the possibility of creating an acoustic cloak using a multilayered elastic cylindrical shell to eliminatethe acoustic field scattered from a rigid cylinder impinged by plane waves. This scattered field is calculated by a semi-analytical code and depends on the dimensional and mechanical characteristics of the elastic layers. Optimization bygenetic algorithm is led to determine the characteristics of the layers minimizing the scattering. Realizable elasticcoatings leading to scattering reduction are eventually proposed.

Lasing characteristics of such structuresare explored for wavelengths from 330nm-830nm and for metal-cladding thicknesses in the range of 5nm-20nm.

09:10 : Transmission of the wave in one dimensional multilayers metamaterial with gainAlireza Keshavarz, Gholamreza Honarasa, Elahe Tahmasebi

We investigate the effect of gain on transmission of electromagnetic waves through the one-dimensional photonic crystals(PCs) with multilayers periodic structure containing negative index materials (NIM) and positive index materials (PIM).Our results show whenever gain increase, we have a large transmission in a particular frequency. Then we can controlthe transmission by controlling the gain. This property can be used for optical filters and switches devices.

The coherent wave trapping and restoration is demonstrated experimentally in a magnetic artificial crystal. Unlike theconventional scheme used in photonics, the trapping occurs not due to the deceleration of the incident wave in a periodicstructure but due to excitation of the quasinormal modes of the spatially localized crystal which is the most effective innarrow frequency regions near the edges of the band gaps of the crystal.

09:50 : Focusing effect measurements of artificial dielectric lens with metal rectangular chips for terahertz wavebandYuki Takebayashi, Takuya Konno, Shouhei Shimada, Fumiaki Miyamaru, John C. Young, Hideaki Kitahara, KeisukeTakano, Masanori Hangyo, Takehito Suzuki

This paper presents the focusing effect measurements of an artificial dielectric lens with metal rectangular chips for theterahertz wave band. The focusing effect is produced by the rectangular metallic chips which macroscopically act aselectrical dipoles. The measurement results are obtained by terahertz near-field spectroscopy. We confirm the focusingeffect at 4.5 mm from the front of the lens at 0.67 THz by measurements.

08:30 : Twisting a focused light spot with a nano-spiralHong Liu, Muhammad Qasim Mehmood, Wei Cheng Qiu, Lin Ke, Hua Jing Teng

We report an experimental and analytical study on a deterministic aperiodic nanostructure (DANS) of spiral, which isable to focus as well as twist light in far field. The 100-nm thick Au spiral structure was patterned by electron beamevaporation and electron beam lithography followed by dry etching. It was optically characterized by confocal imagingmicroscopy with an incident light of 633 nm wavelength. Both experimental and simulation results demonstrate that thiswork provides an innovative way for light manipulation.

08:50 : Nanoscale materials (nanotubes, nanoshells, nanorods, nanodots), applications in cancer research. Acomputational model for study of gold nanoshells’ optical propertiesKatya Simeonova, Ganka Marinova Milanova

Recently, it has been established that nanoscale materials (nanotubes, nanowires, nanoparticles, nanocomosits etc.) playan important role in molecular and cell biology and medicine (nanomedicine). Many researchers (biologists, medicalworkers, etc.) have been attracted by the exceptional properties of these nanomaterials. These nanomaterials possessextraordinary physic-mechanical, optical, electronics, chemical, properties. A typical carbon nanotube, geometry andnanostructure has been given.

09:10 : Simulation and design of a bandpass filter on metasubstratesValdemir Praxedes Silva Neto, Cristhianne Linhares Vasconcelos, Maria Rosa Medeiros Lins Albuquerque, AdaildoGomes d’Assunção

This work presents the analysis of a microstrip bandpass filter on metamaterial substrates. The filter is composed of tworing resonators with quarter-wavelength side-coupled sections. The filter input is provided, as well as the output port,using a quarter-wavelength side-coupled microstrip line section. Simulation by finite element method is proposed toverify the effect of the metamaterial substrate properties on the filter performance and to compare these results to thoseobtained considering isotropic substrate.

09:30 : Metamaterial-Inspired Displacement Sensor with High Dynamic RangeZahra Shaterian, Ali Karami Horestani, Christophe Fumeaux

Split Ring Resonators (SRRs) are ideal structures for realization of compact high resolution sensors. This article presents

76


a displacement sensor based on broadside coupled SRRs coupled to a microstrip line. In contrast to previous SRR-baseddisplacement sensors, the proposed sensor benefits from a high dynamic range limit and since the displacement sensingis based on the shift in the resonance frequency, rather than change in the depth of resonance, the proposed sensorbenefits from a higher immunity to noise.

09:50 : Reconfigurable complementary triangular split ring resonatorG. S. Madhusudan, K. R. S. Ravikumar, D. Sriramkumar, S. Prasad, K. Sridhar, P. H. Rao

Reconfigurable CTSRR loaded in groundplane of microstrip line is presented. Concept of rotated-ring and multiple-splitsare implemented to dynamically tune its resonantfrequency. Reconfigurability is realized using three PINdiodes whosecontrolled by external biasing circuit. CTSRR is initially designed for 900MHz and bandnotch of -15.91dB is obtained.By creating additional metalbridge at 0degree, resonantfrequency is tuned to 1505MHz. On rotating this metalbridge to120 and 240degree positions, resonantfrequency is tuned to 1072MHz and 1113MHz, respectively. Prototype is tested,results are analyzed.

10:10 : Dual band D-CRLH/CRLH rat race coupler with improved performances - a studyIulia Andreea Mocanu, Gheorghe Ioan Sajin

Two ways of obtaining a hybrid rat-race coupler using D-CRLH and CRLH transmission lines are proposed and inves-tigated. The first design method uses relations for asymmetrical D-CRLH and CRLH unit cells, meanwhile the seconddesign method requires symmetrical cells which act only as quarter wavelength transmission lines at the two imposedfrequencies. The first method implies a larger number of cells, rather than only one cell as in the case of the secondmethod.
