Analysis of Electromagnetic Diffraction Phenomena in Arbitrary Linear Media via a Spectral-Domain Technique based on the Wiener-Hopf Method

The study of electromagnetic diffraction in arbitrary linear media holds substantial significance for many practical applications. These types of problems present major challenges in computational electromagnetics, regardless of whether they are tackled using numerical, analytical, semi-analytical, or asymptotic techniques. In this paper, we introduce a new mathematical framework in the spectral domain, utilizing the Wiener-Hopf technique, which effectively addresses the underlying physical phenomena through semi-analytical and asymptotic methods.
