Anomalies in the reflection of an electromagnetic wave from the surface of a ferromagnet in a constant external electric field

Abstract

Anomalies induced by an external electric field in the reflection of a TE electromagnetic plane wave, incident from without on the surface of a semi-infinite ferromagnetic insulator (in Voigt geometry), are studied. The effect these anomalies have on the magnitude and sign of the Goos–Hanchen effect for a beam of plane volume electromagnetic waves with s-type polarization, reflected from the surface of a ferromagnet, is investigated. The results are generalized to a one-dimensional ferromagnet–nonmagnet photonic crystal under the action of a constant electric field.
