Abstract

A theory for the non-linear interactions (induced scattering and mode coupling) of wave-packets of electrostatic waves propagating in a magnetized plasma is presented. A set of coupled equations is derived to describe the changes in the energy distribution within the packets and changes in the distribution of the resonant plasma particles that are accelerated by the non-linear Landau damping (induced scattering). The present theory is proposed as the basis for a numerical analysis of possible electron acceleration in the auroral region where lower-hybrid waves are produced by streaming ions.
