- Abstract
- The effect of dust grain rotation on the damping of a dust acoustic surface wave is investigated for the semi-bounded kappa plasma containing elongated and rotating dust grains. The Landau damping rate is kinetically derived by employing the Vlasov-Maxwell equations and is analyzed for various physical parameters such as the dust grain's angular frequency, the wave number, etc. The result shows that the Landau damping can be enhanced by increasing the dust grain's angular frequency.
