WHTW01 - Factorisation of matrix functions: New techniques and applications

This talk focuses on the effectiveness of Generalized Wiener-Hopf Technique (GWHT) in studying complex scattering and radiation problems constituted of planar and angular regions made by impenetrable and/or composite penetrable materials. First, we present theoretical models in the spectral domain using Generalized Wiener-Hopf equations (GWHEs). Next,  we apply the novel and effective Fredholm factorization technique to get semi analytical solution of the problem by using integral equation representations. The semi-analyticity of the GWHT solution allows physical insights in terms of spectral component of fields. The case study presented in the talk is the electromagnetic field scattering and radiation of a perfectly electrically conducting wedge over a grounded dielectric slab.
