✦ Synopsis
ishes. Again, the effect of the presence of a surface wave is apparent in the Figure . It has also been verified that the copolar component of the field coincides, in the limit p' -+ a/2, with the expressions obtained by the application of the standard Maliuzhinets method, valid at normal incidence.
V. CONCLUSIONS
A uniform high-frequency solution has been presented for three-dimensional diffraction at an edge in a planar anisotropic impedance surface. The solution applies to those cases where the anisotropic surface constitutes a face of either a half plane or a full plane, with the other face perfectly conducting. The particular kind of anisotropic impedance boundary condition adopted for the loaded face is characterized by a vanishing surface impedance in the direction perpendicular to the edge. It is suitable for modeling corrugated surfaces and strip-loaded grounded dielectric slabs, with the direction of either corrugations or strips normal to the edge.
