ABSTRACT
In the course of local heating of plasma particles, the plasma density becomes redistributed by the gradient of the pressure and by die thermal force. The effect plays an important role in, for example, die process of ionosphere heating by intense radio waves. The expulsion of plasma from the wave absorption region results in a change of the reflection point, in rearrangement of die energy input geometry, and in a number of other complicated nonlinear effects. In the laboratory these phenomena are also very important in numerous applications of microwave discharges. In these discharges the thermodiffusion processes greatly influence the plasma parameters, density and temperature profiles, etc.
