Electromagnetic Wave Propagation and Radiation Characteristics of Anisotropic Plasmas
Abstract
A study was made of electromagnetic properties of homogeneous anisotropic plasmas. The propagation characteristics of electromagnetic waves in anisotropic plasmas are examined for propagation parallel to and perpendicular to the applied d-c magnetic field. The existence of very low frequency pass- bands due to ion effects is noted. Faraday rotation due to the earth's magnetic field is considered for the ionosphere and the plasma sheath of a re-entry vehicle. A generalized and exact form of Kirchhoff's law is used to obtain the absorptivity of a plasma from its electromagnetic properties. The absorptivity of an isotropic and anisotropic plasma slab is computed for normal incidence and the effects of electron collision frequency, slab thickness, stop-bands and boundary effects on the radiation spectrum is presented.
