1. AbstractTerahertz irradiation and sensing is being applied lately to a wide
range of fields outside the traditional niches of space science, molecular line spectroscopy, and plasma diagnostics. The motivation is that traditional methods cannot supply a good, or even satisfactory solutions in the terahertz range, due to a much higher diffraction than what is know in the optical regime (infra-red to ultra-violet).This research proposal presents a new technique for converting optical and quasi-optical modes by using Artificial Intelligence. The final purpose is to develop tool for designing system of specialized (printed) mirrors.

2. Introduction-Transmission Line
Transmission line is a cylindric sealed and air dry tube with diameter 250 mm and consist 4 section, perpendicular to each other. At the junction of two pipes are installed confocal mirrors with 90° reflection angel for the central ray, so that all mirrors have a common focus plane.
