摘要：
An analytic theory for the electromagnetic scattering from a coated perfect electromagnetic conductor (PEMC) sphere is developed. The sphere is characterized by its M parameter, and the coating material by its permittivity and permeability, which may attain arbitrary values, including negative ones. The theory is applied to the calculation of various scattering cross sections. It is found that the scattered fields contain cross polarized components, which do not exist in the case of a coated perfect electric conductor (or perfect magnetic conductor) sphere. Symmetry properties of the solutions, which reflect a generalized form of electric-magnetic duality, are demonstrated.
