Finite Element Electromagnetic Scattering: An Interactive Micro-Computer Algorithm

Abstract

The goal of this thesis effort was to develop an interactive electromagnetic scattering algorithm for personal computer use in the analysis and computer aided design (CAD) of scattering structures. Extensive interactive computer aided design type features have been added to a previously developed finite element computer algorithm which considers scattering from inhomogeneous axisymmetric objects. These computer aided design features allow structures composed of multiple dielectric and/or magnetic materials to be graphically constructed or modified by the user by way of either a keyboard or mouse interface. Bistatic scattering patterns are graphically presented upon completion of the computation for a variety of user specified incident field orientations. Keywords: Electromagnetic scattering, Finite element algorithm, Azimuthal potentials, Computer aided design.
