Efficient integral equation based analysis of scattering from PEC-anisotropic bodies

The paper presents an integral equation (IE) formulation for analyzing perfectly electrically conducting (PEC) bodies with anisotropic coatings. Such analysis is becoming increasingly relevant as anisotropic coatings are becoming common in many applications, for instance, in ferrite coatings. Likewise, recent advances in metamaterials and nanocomposites has opened the door to the possibility of engineering materials with specific responses. Consequently, there is a need for developing methods that enable the analysis of complex bodies containing both. PEC structures and materials. The mathematics necessary to enable this analysis is developed. The paper elucidates the derivation of the integral equation and elaborates upon the evaluation of integrals required for constructing the method of moments matrix. Some numerical validation of the proposed scheme is provided.
