Abstract

An efficient and accurate moment method analysis of a parallel-plate waveguide with one single hard wall using the aperture integral equation (AIE) and the CG-FFT method is presented. This approach is perfectly applicable to new realizations of soft/hard surfaces apart from the classical corrugations. A realization of this waveguide with classical corrugations has been analyzed here. The results corroborate the unique property found for this waveguide: the simultaneous propagation of several independent degenerate quasi-TEM waves.
