Dispersion of electromagnetic waves in active moving plasma

Abstract

Abstract Observable radiation contains information on its'source as well as on the medium through which it has propagated. Measuring the angular broadening suffered by crossing radiation through any magnetoactive plasma, it is possible to obtain important conclusions about the physical plasma parameters, such as the electron density distribution, magnetic field and macroscopic plasma velocity. In this work we describe the physical picture for propagation of the electromagnetic waves in the magnetoactive plasma, taking into account the macroscopic velocity of the system. In moving magnetoactive plasma, the relations for the dielectric permittivity tensor, the dispersion equations and the refractive indexes are established. These results can be evaluated, for example, by the determination of the angular displacement of the radiation coming to us from far radio sources, after passing through solar corona and solar wind plasmas.
