Wiener-Hopf Analysis of the Scattering from an Abruptly Ended Dielectric Slab Waveguide

Abruptly ended dielectric slabs are important components in several areas of applied electromagnetics. For the study of these geometries, a variety of analytical methods have been proposed in the past. In this paper we formulate the problem in terms of Wiener Hopf equations and we apply the novel and effective semi-analytical solution technique known as Fredholm factorization
