improvement in transition loss by adding dielectric layers in Hollow waveguide in THz Rangeاولین کنفرانس بین المللی دستاوردهای نوین پژوهشی در مهندسی برق و کامپیوتر

Terahertz (THz) radiation has important applications in spectroscopy, and space science. Research on reducing material absorption in Terahertz (THz) waveguides has led to development of guiding structures with transmission losses as low as 0.1 dB\m. Among waveguides that exhibit low loss at THz frequencies are the dielectric lined hollow cylindrical metallic waveguides. In this contribution we overview properties of dielectric–lined hollow cylindrical metallic waveguides for THz waves, their design principles and the fabrication process.<\div>
