A numerical comparison between EFIE/MoM and CCD methods for EM scattering in two dimensions

Abstract

Two methods for calculating the electromagnetic radiation scattered by a perfectly conducting object: the Electric Field Integral Equation formulated within the Method of Moments, and the Clifford-Cauchy-Dirac technique; are compared numerically for a particular test case. Both methods involve the calculation of fields over the surface of the scatterer from integral equations; one integral with a kernel of Green's functions and the other with a Cauchy kernel. Although both start with Maxwell's equations the two methods differ fundamentally in several ways.
