Abstract
The energy transport of circularly polarized waves (CPW) in bi-kappa distributed plasmas is studied using kinetic theory. Energy flux is examined by taking into account the wave-particle interaction. We investigate how the energy flux is affected by the variation of thermal speed, temperature anisotropy (the parallel and perpendicular temperatures are different with respect to the direction of ambient magnetic field, i.e., T⊥ > T∥), index κ and the wave frequency. It is found that the CPW transport their energy rapidly over distances for smaller values of the thermal speed, the index κ and the wave frequency, whereas for low values of temperature anisotropy the waves deliver their energy slowly. Thus the above-mentioned parameters play an important role in the transport of wave energy. Possible applications of the present analysis are discussed.
