Surface-integral equations for electromagnetic scattering from impenetrable and penetrable sheets

The authors discuss integral equations for electromagnetic-scattering problems involving open (in general, non-planar), thin, impenetrable and penetrable sheets, characterized by two different reflectivities for their two faces. A unified formulation is presented for both systems in terms of coupled surface-integral equations for two tangential surface-polarization currents. Numerical results for some relevant representative scatterers are given.<
