Abstract

The analysis of electromagnetic scattering from a large, deep, and arbitrarily-shaped open cavity is difficult because of a large number of unknowns resulting from the discretization of the cavity. A technique is based on finite element method (FEM), which is capable of handling arbitrary geometries and complex material composition, is developed to solve this problem. The FEM mesh at the cavity aperture is terminated in an exact manner by the boundary integral method. The technique exploits the unique features of the finite element equations and the unique features of the scattering problem by a large and a deep cavity. It is designed to use minimal memory, which is proportional to the aperture size of the cavity and independent of the depth the cavity.
