Electromagnetic Wave Reflection from a Metal-Backed Non-Uniform Plasma Layer for Non-Normal Incidence

摘要

The calculation of the reflection coefficients for a plane transverse electromagnetic wave incident non-normally on a non-uniform plasma layer with a metal-backing wall is discussed. It is assumed that the plasma properties (plasma frequency and electron collision frequency) vary spatially only in the direction normal to the metal wall. The plasma layer is treated as a spatially non-uniform lossy dielectric material. For non-normal incidence, it is most convenient to consider an arbitrarily polarized incident electromagnetic wave to be composed of TE(transverse electric) and TM modes. The reflection coefficient for each of these different modes is then found separately. (Author)
