A Green ’ s Function Approach to Calculate Scattering Width for Cylindrical Cloaks

─The anisotropic material properties of cylindrical cloaks can be simulated using thin, concentric layers of homogeneous, isotropic material. A Green's function for a line current in the presence of a layered PEC cylinder can be used to calculate the scattering width from a cloaked PEC cylinder with a significant improvement in computational efficiency compared to solutions obtained using the finite element method.
