Abstract
The application of edge-elements for modeling three-dimensional inhomogeneously filled cavities is presented. Explicit representations for the two element matrices (S)/sub e/ and (T)/sub e/, are provided in order to facilitate the implementation of the FEM formulation. Also included are the results of a numerical experiment that investigates the rate of convergence of the computations of the dominant resonance frequency of a rectangular cavity when the edge-element formulation is used.<>Keywords
