Resolution of 2D Scattering Problem Using Method of Moment and RWG Functions

Abstract

This paper presents a novel algorithm for analyzing transient radiation from an arbitrary shape illuminated by an incident electromagnetic wave. The algorithm is based on spatiotemporal Integral Equation (Electric Field Integral Equation) to predict the transient response of the antenna. The Laguerre functions are used as temporal basis. In order to simplify the space modeling, we reformulate the space basis RWG. This basis is expressed in polar coordinate that defines by pairs of adjacent triangular. The later presents the analyzed sub-domain characterized by their triangle's centroid. Numerical results that validate and demonstrate the efficacy of the proposed algorithm are presented.
