Wiener-Hopf formulation of the scattering by a stepped wedge

This paper presents the formulation and the procedure to get the solution of the scattering problem constituted by a PEC wedge connected to a PEC step structure. We formulate the problem in terms of generalized Wiener-Hopf equations (GWHEs) in spectral domain whose solution is obtained through Fredholm factorization with the help of circuital representations of the angular region and layered region
