Kinetic approach on the DIA wave propagation in a non‐extensive distributed dusty plasma

다국어 초록 (Multilingual Abstract)

The Landau damping of the dust ion‐acoustic wave (DIAW) in a dusty plasma with non‐extensive distributed components is analysed relying on the kinetic approach. The electron, ion, and dust particles are effectively modelled by the non‐extensive distribution function of the Tsallis statistics. For a collisionless plasma with different values of plasma components indices, the general dispersion relation is achieved, and the non‐extensivity effects on the frequency, as well as the Landau damping of the DIAW, are studied. We show that for q→1, the preliminary results of the Maxwellian plasma are obtained. The decrease of wave damping is achieved by increasing the coefficient q index and the ion‐to‐electron density ratio. The damping rate also increases with an increasing ion‐to‐electron temperature ratio.
