Heating mechanism of self‐interaction of potential surface waves in a warm nonisothermal plasma bounded by metal

The influence of electrons heating in the high‐frequency potential surface wave (SW) field on dispersion properties of the considered SW is studied in this paper. High‐frequency SW propagate at the interface between a warm nonisothermal plasma and a metal. The nonlinear dispersion relation for the SW is derived and investigated. The obtained results are valid in both semiconductor and gaseous plasmas in a weak heating approximation.
