The Reflection Coefficients of an Anisotropic Impedance Plane That Converts Several Incident Waves Into an Arbitrary Number of Reflected Waves at Given Polarizations

In the paper, the reflection coefficients for non-uniform anisotropic imedance surface, that reflects several incident plane waves simultaneously into a required number of chosen directions with co-polarization and cross-polarization are derived for the first time. The impedance is introduced as a dense lattice of orthogonal stripes, which are placed closely to each other and are oriented arbitrarily on the surfaces. Expressions for the scattering diagrams are derived.
