QUANTUM ELECTRON PLASMA AND S-WAVE INTERACTION WITH METAL HALF-SPACE

Abstract

Aim. We study the influence of kinetic and quantum wave properties of degenerate electron plasma on the S-wave interaction with metal half-space. Methodology. The dependence of the energy absorption coefficient of S-waves by metal half-space on the radiation frequency not exceeding the plasma frequency is studied and analyzed using theoretical formulae that take into account the transverse dielectric permittivity of the plasma of conduction electrons. Results. It is shown that at the usual values of the collision frequency of conduction electrons, the results for quantum electron plasma differ from the results for classical electron plasma and for classical electron gas. In the case of small values of the collision frequency of electrons, the results for quantum and classical electron plasmas almost coincide at the frequencies less than the plasma frequency, and differ at frequencies near this frequency. Research implications. The obtained results can be used in the theoretical study of interaction of radiation with metals, as well as in the development of optical devices using metal radiation detectors.
