SURFACE IMPEDANCES OF A FLAT LAYER OF A MEDIUM WITH A MIRROR-SYMMETRIC DIELECTRIC RESPONSE FUNCTION

Abstract

The electromagnetic field of a plane monochromatic wave inside a flat layer of a uniform medium possessing a spatial dispersion and having a mirror-symmetric dielectric response function is considered. The method of Fourier series decomposition is used to evaluate the surface impedance of the layer in the cases of P- and S-waves. The obtained equations for the surface impedances coincide with those from works of Kliewer and Fuchs for a flat layer of electron plasma and describe correctly the surface impedances of a flat layer of a medium without spatial dispersion.
