Hybrid finite-element methodologies for antennas and scattering

Abstract

This paper is an overview of the finite-element method (FEM) as applied to electromagnetic scattering and radiation problems. A brief review of the methodology is given with particular emphasis on new developments over the past five years relating to feed modeling, parallelization, and mesh truncation. New applications which illustrate the method's capabilities, versatility, and utility for general purpose application are discussed.
