Abstract

A three-dimensional treatment of transmission line discontinuity problems by the finite difference method is presented. Maxwell’s equations are solved in the frequency domain by solution of a boundary value problem. The presented method allows to compute the scattering parameters of an arbitrary structure, including coupling of higher order modes. The general formulation and the procedure of the method is described. Verification calculations are given and results for different microstrip discontinuities are included for the lossy and non-lossy case.
