1 May 2016 | Abstract: | In this paper we derive the dielectric tensor for a plasma containing
particles described by an anisotropic superthermal (bi-kappa) velocity
distribution function. The tensor components are written in terms of the
two-variables kappa plasma special functions, recently defined by Gaelzer and
Ziebell [Phys. Plasmas 23, 022110 (2016)]. We also obtain various new
mathematical properties for these functions, which are useful for the
analytical treatment, numerical implementation and evaluation of the functions
and, consequently, of the dielectric tensor. The formalism developed here and
in the previous paper provides a mathematical framework for the study of
electromagnetic waves propagating at arbitrary angles and polarizations in a
superthermal plasma. | Source: | arXiv, 1605.0279 | Services: | Forum | Review | PDF | Favorites |
