WKB SOLUTION 4x4 FOR ELECTROMAGNETIC WAVES IN A PLANAR MAGNETICALLY ANISOTROPIC INHOMOGENEOUS LAYER

摘要

In the paper, an oblique incidence of a plane electromagnetic wave on a planar magnetically anisotropic inhomogeneous layer is considered. We consider the case when all the components of the magnetic permeability tensor are non zero and vary with distance from the interface of media. The WKB method gives a matrix 4×4 solution for the projections of the electromagnetic wave fields during its propagation. The dependence of the cross-polarized components on the orientation of the anisotropic medium relative to the plane of incidence of the medium is analyzed.
