Nonlinear Perturbations of Cold Magnetized Plasma Generated by Radiation Pressure Forces

摘要

The nonlinear perturbations of plasma density and velocity are derived for the case of a quasi monochromatic wave packet propagating perpendicularly to a magnetostatic field. Radiation pressure forces arising from the time dependence of the wave amplitude are included. Thermal pressure and collisional effects are neglected. The basic equations and assumptions are formulated and the time averaged electric current density is established. The plasma motion in the direction of wave propagation is studied for two particular cases and the results obtained are discussed.
