Solution and Stability Analysis of A New Integral Equation for the Transient Scattering by A Flat, Rectangular Conducting Plate

Abstract

The electric-field integral equation (EFIE) is a common tool for determining scattered or radiating fields emanating from a perfectly conducting, open surface. In this type of approach the induced surface current and/or charge density are solved from the integral equations, and, subsequently, the scattered electromagnetic field is determined at any given point by evaluating the integrals in a conventional integral representation. Advantages of this approach are that the radiation condition is accounted for inherently, and that only two-dimensional surface currents and/or charges need to be computed over the area of the scattering surface, instead of three- dimensional electromagnetic fields over a volume surrounding that surface.
