Scattering of high frequency waves due to density fluctuations

A theory of the scattering of high frequency waves by density fluctuations is formulated. In the plasma interior, the usual wave kinetic equation is used to derive a Fokker–Planck equation with the background fluctuations assumed to be given. The possible excitation of electrostatic drift waves by the high frequency waves is also considered and a quasi‐linear equation is demonstrated. Stochastic changes in the wave frequency and the group velocity result in the corresponding diffusion and friction in phase space.
