MULTI-FLUID ANALYSIS OF WAVE PROPAGATION IN A MAGNETOPLASMA,
Abstract
A theoretical investigation has been conducted to determine the propagation characteristics of small amplitude, hydromagnetic waves in a magnetoplasma-filled waveguide at signal frequencies approximately equal to or less than the ion-cyclotron frequency. An inviscid, quasi-one-fluid analysis was made which includes the effects of Hall field. A more complex analysis was made which incorporated the effects of unequal electron and ion temperatures, space charge, diffusion, and current inertia. The method of approach was then generalized to permit treatment of neutral particle dynamics. This included partial ionization of the plasma and the existence of a sheath of neutral particles at the walls of the waveguide. A numerical study was also conducted to establish the significance of multi-fluid effects on the phase velocity, attenuation, cutoff frequency (where pertinent), and wave patterns. (Author)
