Evaluation of Singular Electric Field Integral Equation (EFIE) Matrix Elements

Abstract

The electric field integral equation (EFIE) solution for scattering from an arbitrary three-dimensional geometry was published by Rao, Wilton, and Glisson (RWG) in 1982. For electrically large problems, with large systems of equations, the physical fidelity of the solution can be improved with increased numerical accuracy of the Galerkin inner products which populate the method of moments (MoM) impedance matrix. A new treatment of these inner products is presented here which improves the accuracy of the singular surface integrals that result from the Galerkin formulation.
