摘要：
The dispersion relations for the weakly magnetized perpendicular propagating modes (O-mode, X-mode, and upper hybrid mode) based on the ultra-relativistic Fermi-Dirac distribution function with chemical potential are derived using the Vlasov-Maxwell model. The results are presented in terms of Polylog functions without making any approximation. It is found that as the ratio mu/T is increased, the cutoff points shift downward. A comparison is also performed with the previously derived results for ultra-relativistic Maxwellian distribution. (C) 2015 AIP Publishing LLC.
