Abstract

Electromagnetic wave analysis of two-dimensional metal waveguides is carried out by the finite element Galerkin time domain method (FEGTD). A TE₁₀ wave excites a waveguide in which a rectangular or circular dielectric post is loaded, and the time course of the spatial distribution of the electromagnetic wave is calculated. We use Galerkin´s method to discretize Maxwell´s scalar equations directly in the spatial domain and solve the linear system of equations, which is a first-order differential equation with respect to time. To solve open-region problems, we postulate attenuated one-directional traveling waves in non-reflection absorbing regions arranged at the two terminal ends. Isoparametric finite elements and attenuated infinite elements are used.
