ANÁLISE DE PROBLEMAS DE ESPALHAMENTO ELETROMAGNÉTICO INVERSO 2D VIA FEM-BEM E SSGA

J. A. Vasconcelos, F. S. G. Lisboa

Abstract


A new approach for the analysis of two-dimensional inverse electromagnetic scattering problems is addressed in this paper. The technique presented here is based on the finite element-boundary element hybrid method (FEM-BEM) coupled with the SSGA Steady State Genetic Algorithm. The hybrid FEM-BEM overcomes the disadvantages of both FEM and BEM when dealing separately with problems whose domain is composed by two or more regions, being one of them constituted by inhomogeneous material and the other being open (freespace). The inverse problem analysed in this article consists in determining the cross-section shape of the cylindrical dielectric scatterer from the knowledge of the far field pattern.
