Scattering by a PEC wedge on a dielectric substrate

A perfect electric conductor wedge lying on a dielectric half-space is analyzed, in the frequency domain. The structure is excited by a plane wave coming from the free space region. The problem is formulated using generalized Wiener-Hopf equations and an approximated solution in terms of spectral quantities is proposed by discretization of Fredholm integral equations. Numerical results for several geometries will be presented and discussed at the conference.
