Abstract: | The nonlinear coupling of intense radio waves with the low-frequency electrostatic perturbations of multi-component collisional plasmas is considered. Assuming the presence of two distinct groups of electrons and singly charged ions, we obtain equations for the radio wave sidebands and plasma slow motions that are driven by the combined effects of the radiation pressure and the differential Joule heating of the electrons. The mode coupling equations are useful for studying various types of stimulated scattering instabilities and envelope soliton formation. The relevance of our investigation to the simultaneous generation of density and temperature fluctuations by high-power radio waves is pointed out. |
