Nonspecular Effects That Occur as a Quasi-Plane Wave Passes through a Finite Photonic Crystal with an Asymmetric Polariton Spectrum

Abstract

First-order nonspecular effects emerge in the plane of layers for both reflected and transmitted waves (particularly the spatial and angular Goos–Hänchen effect) for a quasi-plane of the TM (or TE) type normally incident from outside on a finite one-dimensional magnetic photonic crystal with a spectrum of normal magnetic polaritons, asymmetrical with respect to the inversion of the direction of wave propagation.
