Wiener-Hopf formulation of an unaligned PEC wedge over a stratification

This paper deals with the problem of evaluating the electromagnetic field of a perfect electrical conductor (PEC) wedge over stratified media. The particular case wherein one face of the wedge is perpendicular to the direction of stratification has been previously considered and solved by using the generalized Wiener-Hopf technique [1]. In this paper the directions of the two faces of the wedge are arbitrary. We formulate the problem in terms of generalized Wiener-Hopf equations (GWHE) and we propose a solution method based on the reduction of the GWHE to Fredholm integral equations of second kin
