Electromagnetic scattering by arbitrarily shaped two-dimensional perfectly conducting objects coated with homogeneous anisotropic materials

Combined-field surface integral equations are applied to analyze electromagnetic scattering from coated perfectly conducting objects. The conducting core and the homogeneous anisotropic coating layers covering it are assumed to be two-dimensional and of arbitrary shape. Furthermore, individual layers of anisotropic material constituting the composite clad structure are allowed to have distinct medium tensor properties. Numerical solution of the resulting integral equations is facilitated by the method of moments. Equivalent surface currents on the metal core and the jacket surface are computed, and along with the corresponding radar cross section are presented for a variety of scattering geometries.
