A PO driven iterative solution of MFIE for large scatterers

Abstract

Despite enormous expansion of numerical techniques in electromagnetics, analysis of large scatterers still is a challenging task. MoM is not sufficiently efficient at high frequencies, PO and GTD based techniques give acceptable results only for certain class of problems, while hybrid techniques still evolve. In this paper we present a new method for analysis of large scatterers, based on iterative solution of MFIE. Simple concept and low memory requirements of the method are followed by reasonable accuracy of results.
