Fundamental analysis of electromagnetic wave scattering from multi-layered window glass in multi-frequency band

Abstract

In this paper, we examine electromagnetic wave scattering from a window glass in multi-frequency band. Here we focus on scattering from three-layered window glass, which is made of sandwich dielectric structure (dielectric-air-dielectric structure). The scattering features from the layered glass for the wide bands are in detail examined by using ‘collective ray solutions’, which are high frequency asymptotic approximate solutions and can bundle the the multiple reflected rays in each layer into the primary scattered fields. Here we discuss on the resonance-like phenomena as low reflection return occurs, by comparing with the results of primary scattered model and single layer slab model.
