Joshi, G H

A linear macroscopic electrodynamic analysis of a fully ionized, collisionless, magnetized electron-ion drifting and/ or stationary plasma was carried out. The analysis suggests two possible mechanisms which will convert the d-c energy of the driftfng plasma to the electromagnetic energy and vice versa. The first mechanism involves the interactions between the circularly polarized transverse electromagnetic waves supported by an unbounded plasma which streams along the ambient magnetic field through an ambient stationary plasma. The other mechanism is based on the coupling between the quasi-transverse electromagnetic waves and the quasi-longitudinal space charge waves supported by a bounded plasma which drifts along the ambient magnetic field. This mechanism is restricted only at a frequency which is slightly below the ion cyclotron frequency. The two mechanisms might find an application in (a) the heating of the thermonuclear plasma and (b) plasma propulsion. The mechanism likewise might enable one to explain some of the low-frequency whistler type radio noise. Preliminary results are also presented on (a) the plasma waves in an inhomogeneous plasma and (b) the microscopic analysis of the drifting plasma. (auth)
