Thermal Enhancement of Absorption of EM Radiation in a Hot Magnetoplasma Slab

Abstract

The problem of kinetic thermal effect on propagation characteristics of electromagnetic (EM) radiation incident on a hot Maxwellian magnetoplasma slab near a metallic surface is investigated. Reflection, absorption, and transmission rates are calculated numerically for a set of parameters that may be suitable for stealth plasma together with other applications. Numerical results, compared with those obtained using cold and warm plasma fluid models, show thermal enhancement of absorption of a transverse right circularly polarized EM wave propagating along an applied magnetostatic field within a slab of Vlasov plasma. Propagation characteristics of the right circular wave with a full kinetic expression for the refractive index are recovered in the limiting cases of magnetically biased cold and warm plasmas.
