Abstract

A generalized procedure is presented for obtaining the propagation characteristics of waveguides having a shape defined by steps along the Cartesian axes. The conductor and dielectric regions that compose the structures may be lossy and/or anisotropic. Although we consider only two-dimensional (2D) examples here, the approach applies to three-dimensional (3D) waveguides and to any discontinuities that may be present. This guided-wave formulation is novel because it applies 2D basis functions to represent the 3D polarization current in the dielectric regions.
