✦ Synopsis

Fields scattered by a lossy dielectric wedge for a plane-wa¨e incidence are calculated. Reflected and refracted fields are obtained by inhomogeneous plane-wa¨e tracing in a lossy medium, while the edgediffracted fields of the physical-optics approximation are accurately corrected by adding the multipole line sources at the edge of the wedge to satisfy the extinction theorem. This solution pro¨ides accurate numerical results for the scattered fields when the loss tangent of the wedge medium is less than about 10, which is guaranteed by the smallness of the extinction integral.

In this paper, electromagnetic plane wave scattering by a gap on a ground plane is analyzed. First, a rectangular trough is used as a gap model to obtain the rigorous representation of the scattering field based on a method by Kobayashi and Nomura. Then the simple formulae for the case when the aper
