Ray analysis of electromagnetic scattering for a coupled parallel plate waveguide

Abstract

The problem of electromagnetic plane wave scattering by a coupled, perfectly-conducting, semi-infinite two-dimensional parallel plate waveguide, with a thin, uniform layer of lossy material on its inner walls is analyzed using a a high frequency method. When the waveguide is illuminated by a plane wave, the ray fields are coupled into the waveguide from the exterior region and found via the Uniform Geometrical Theory of Diffraction (UTD) ray method.<>
