EM scattering by metallic half plane loaded by anisotropic face with arbitrarily oriented anisotropy axes

Electromagnetic scattering by the edge of an anisotropic impedance half plane with a perfect electric conducting (PEC) face is analysed. Although only valid at normal incidence, the solution has some interesting features with respect to previous analyses presented for anisotropic impedance canonical configurations. Indeed, it allows the investigation of the case in which the principal anisotropy axes on the loaded face are arbitrarily oriented with respect to the diffracting edge. The specific tensor surface impedance considered exhibits a vanishing surface impedance along a principal anisotropy axis and an arbitrary one in the orthogonal direction
