Landau damping of electrostatic modes in nonthermal plasmas
The dispersion relation (DR) and Landau damping of basic electrostatic modes propagating in an electron-ion plasma modeled by a Cairn's distribution with a spectral index α are kinetically investigated. In the high-frequency range, i.e., ω / k > v t e , the DR and Landau damping of the elect...
