Abstract
Dust-Acoustic Surface Wave Stability in Dusty Lorentzian Plasmas Taejoon Kim and Myoung-Jae Lee Department of Physics, Hanyang University, Seoul 133-791 (Received 15 May 2008) The dispersion relation of dust-acoustic surface waves (DASW) propagating on the interface between a vacuum and a semi-bounded dusty Lorentzian plasma is derived using a standard kinetic approach. The real and the imaginary parts of the wave frequency !r+ i are obtained as functions of the scaled wave number p kx D, where = (2 3)=(2 1) with being the spectral index of the Lorentzian distribution function and D being the total Debye length of ions and electrons. The wave displays Landau damping for all wave numbers, but can be signi cantly reduced as the wave number increases. The maximum damping rates are obtained as functions of the spectral index and the ion-to-electron density ratio. PACS numbers: 52.35.-g
