Obliquely Incidence Scattering by an Anisotropic Impedance Wedge: Surface Waves and the Diffraction of the Surface Waves

Asymptotic high-frequency expressions of the total fields excited by a plane wave obliquely incident on an anisotropic impedance wedge are derived in the framework of the uniform geometrical theory of diffraction (UTD). The total fields include the geometrical optical (GO) field, the surface wave (SW) field, the diffraction fields of the GO and SW field, which can express the scattering mechanism integrally.
