Advanced Electromagnetic Modeling

Abstract

This report presents a fast, high-order hybrid volume/surface integral equation formulation developed under the DARPA VET program for the electromagnetic scattering by composite material targets. The solution is based on a high-order method of moment discretization with quadrature point collocation scheme, shown to be equivalent to the Locally Corrected Nystrom formulation. The general solution procedure has been incorporated into the University of Kentucky Mat-Scat software. Mat-Scat also supports fast iterative solvers, including the Quadrature-Sampled Pre-Corrected FFT and the Fast Multipole Method. Also discussed is a high-order mesh processing software, Mesh Tool, used to generate high-order mesh descriptions of complex objects for simulation via Mat-Scat.
