A New Multi-Level Power Series Solution Algorithm to Solve Electrically Large Electromagnetic Scattering Problems Applicable to Conducting Bodies

Recently, a power series solution method was proposed to obtain the induced current distribution and radar cross section (RCS) for electrically large conducting bodies [1] . The method is based on the well known method of moments (MOM) and retains all the advantages of the conventional MOM and is still applicable to electrically large bodies. In this work, we extend this approach to a multi-level algorithm, which generates more efficient solution with fewer computer resources.
