An introduction of the generalized Wiener-Hopf technique for coupled angular and planar regions

Abstract

This paper presents the formulation of the electromagnetic problem constituted of coupled angular and planar regions by using the generalized Wiener-Hopf technique. The paper introduce also the technique to obtain a solution of the problem by reducing the factorization problem to Fredholm integral equation. The test case of a PEC planar waveguide filled by a dielectric medium that opens to a PEC angular region is presented.
