摘要：

A heuristic uniform theory of diffraction (UTD) corner and wedge diffraction coefficient for predicting electromagnetic scattering by a thin lossless anisotropic slab is presented. An approach based on modifying UTD corner and wedge diffraction formulations for a half-plane with the reflection and transmission coefficients of an anisotropic medium is proposed. The formulation works for both uniaxial and biaxial media and the final expressions are in closed form and easy to implement in ray-tracing software. Numerical results for various scattering problems showing excellent agreement with reference solutions are provided.
