摘要：

A study is made of the effect of the heating of plasma electrons in the field of a potential surface wave on the wave dispersion properties. The wave is assumed to propatgate along the boundary between a metal and a finite-pressure plasma. Different mechanisms for electron energy losses are considered in the weak beating approximation. The spatial distribution of the plasma electron temperature under nonlocal heating conditions is derived on the basis of the electron energy balance equation. Expressions for the spatial damping rate and the nonlinear shift of the wavenumber are analyzed for different values of the plasma parameters. The results obtained are valid for both semiconductor and gaseous plasmas. (C) 2003 MAIK "Nauka/Interperiodica".
