A coupled integral equation solution of chirally coated conducting bodies

Abstract

This paper presents a coupled surface integral equation (CSIE) solution of electromagnetic scattering by chirally coated conducting bodies with arbitrary shape. The equivalence theorem combined with the field splitting scheme is used to formulate the fields within chiral media in terms of two sets of equivalent electric and magnetic surface currents. The boundary condition is enforced on the interface between conducting bodies and chiral media. A system of coupled matrix equations are then obtained and numerically solved using the method of moments. The calculated data for a conducting sphere coated with chiral material is compared with the exact solution and excellent agreements are observed
