Scattering of Electromagnetic Radiation by a Perfect Electromagnetic Conductor Sphere

An analytic theory for the electromagnetic scattering from a perfect electromagnetic conductor (PEMC) sphere is developed. The PEMC is characterized by a single parameter M, where M = 0 reduces to the perfect magnetic conductor (PMC) case and the limit M → ∞ corresponds to the perfect electric conductor (PEC) case. The theory allows for the occurrence of cross-polarized fields in the scattered wave, a feature which does not exist in the standard Mie scattering theory. The application of the theory to the calculation of the scattering cross section is presented. As an example we evaluate the relative contributions of the co-polarized and the cross-polarized fields to the backward and forward scattering cross sections.
