Abstract

A conformal mapping technique for single-groove guide is discussed and applied to grooves of V-shaped cross section. The approach is to transform the V-groove guide into the parallel-wall guide filled with a nonisotropic and nonuniform medium. Experimental measurements at X-band and 100 GHz confirm the theoretical predictions. The characteristic equation and scale factor of the fundamental mode are developed, and its propagation characteristics are given graphically for several normalized groove dimensions
