Electromagnetic scattering of plane waues obliquely incident on the edge of a planar anisotropic impedance surface is analyzed. A rigorous analytical solution, obtained by applying a procedure similar to that originally proposed by Maliuzhinets, is derived with reference to a couple of pariicular geometrical conjgurations. These latter are relerant to the case in which the anisotropic impedance surface is truncated to originate on either the edge of a half-plune, the other face being perfect electric conductor, or on a planar junction between the same anisotropic surface and a perfectly conducting plane. The exact integral representation for the total field is then asymptotically er,aluated in the conlext of the uniform geometrical theory of diffraction (UTD). The particulur kind of anisotropic surface impedance considered for the loaded face is suitable for modeling corrugated surfaces or strip-loaded grounded dielectric slabs, when the direction of either corrugations or strips is petpendicular to the edge.
