Reducing Bore and Total Transmission loss in Metal/Dielectric Coated Hollow Flexible Terahertz Waveguide

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
