MAGNETOHYDRODYNAMIC MODE COUPLING INVESTIGATION

Abstract

Wave phenomena was studied in a magnetoplasma to ascertain which of these phenomena might be used in the design of future space communication systems. Major emphasis was placed on several broad aspects of plasmaelectrodynamics: investigation of the characteristic modes, coupling of modes by plasma unhomogeneities, propagation of non-planar electromagnetic waves in a magnetoplasma, focusing caused by the anisotropy of the medium, and propagation of electromagnetic waves in an unhomogeneous plasma. A rather striking demonstration of the effects of a magnetoplasma on wave propagation was provided by a numerical study in which constant plane surfaces of a non-plane monochromatic wave in an infinite homogeneous magnetoplasma act to strongly focus electromagnetic energy into directions normal to the stationary impressed magnetic field.
