Cross-polarization of electromagnetic waves reflected by anisotropic gradient planar structures

Abstract

The results of calculating the moduli of the coefficients of the electromagnetic wave reflection matrix (EMW) at the boundary of an inhomogeneous anisotropic medium with torsion using the matrix form of the Wentzel-Kramers-Brillouin (WKB) method are presented. The effect of the orientation of the optical axis and the torsion angle on the polarization of the waves propagating in the medium and on the off-diagonal coefficients of the reflection matrix is shown.
