An analysis for electromagnetic response of a PEC of spherical shape having an uniform concentrical coating of biisotropic medium is rigorously formulated by constructing spherical vector wavefunctions. For the prescribed radius and thickness of the coating, an anisotropic impedance boundary condition at the outer surface of the coating is developed in the spectral domain, which is useful for solving the scattering problem of the biisotropically coated spherical PEC structure.
