Full-wave analysis of waveguides involving finite-size dielectric regions
Abstract
A moment method is presented for handling arbitrarily shaped 2-D and 3-D waveguides that involve conductors, finite-size dielectric regions, or both. A novel procedure for modeling the dielectric allows 2-D rooftop functions to represent both the 3-D polarization current i n the dielectric and the surface current on the conductors. Examples include microstrip and dielectric waveguides. Numerical convergence, consistency with physical principles, and agreement with the literature are demonstrated.
