Abstract
For pt.I see ibid., vol.25, no.6, p.665 (1983). The authors review various methods for obtaining an expression for the ponderomotive force on a magnetized plasma; these methods are based on a fluid, kinetic, or a stress-tensor approach. They propose a new method which employs a fluid-dielectric model of the plasma; this method seems to be simple and generally applicable. They first of all calculate an expression for nonstationary waves in an isotropic plasma and find agreement with earlier results. They then derive an expression for the ponderomotive force in a magnetized plasma for the case of stationary waves and compare their result with earlier attempts to obtain such an expression.
