Abstract :
The full-wave mode-matching method employing the similarity transformation is used to derive the eigenvalue equation for the periodic bumpy regions that model the surface roughness of a WR-10 (75-110-GHz) waveguide. For the case study reported, attenuation losses increased by approximately 60% (36%) at 75 GHz (110 GHz).<>
