Abstract

A novel mixed spectral domain method is applied to the analysis of generalized dielectric-loaded ridged waveguides. Auxiliary structures are constructed for formulating the spectral Green's functions and applying the spectral immittance method. Magnetic surface currents at apertures are identified as unknowns. Mixing different spectral domains existing on the two sides of an aperture in a spectral Galerkin approach leads to the characteristic equations required for the dispersion analysis. Representative results are obtained to illustrate the application of the method. It is concluded that the proposed method appears to be suitable for efficient analysis of more complicated transmission structures which involve variations in the side-wall separations in a rectangular waveguide.
