Conventional waveguides present a high attenuation in the THz band due to the high ohmic losses on metallic surfaces and the high absoprtion in dielectric materials. GRE analyzes and proposes waveguides that palliate these problems. Moreover, GRE studies and proposes efficient feeding structures for the newly proposed waveguides, as well as modifications of these waveguides to reduce the losses on curved paths.
