Wiener-hopf formulation of the scattering by a PEC wedge over an half dielectric grounded slab

This paper presents the formulation of electromagnetic problems constituted of inhomogeneous coupled angular and planar regions by using the Generalized Wiener-Hopf Technique (GWHT). In particular the paper is focused on the scattering of a perfectly electrically conducting (PEC) wedge in contact with an half dielectric grounded slab. The solution method is based on deriving the Wiener-Hopf formulation and on using the Fredholm factorization. In this case the presence of inhomogeneous regions introduces further difficulties.
