Abstract
CASTRO, E; PUERTA, J; MARTIN, P and CERECEDA, C. Landau damping in bi-dust ion-acoustic waves. Rev. mex. fis. [online]. 2006, vol.52, suppl.3, pp.224-226. ISSN 0035-001X.
Ion acoustic dust waves in a bi-dust plasma are analyzed in this paper. In order to model this system, we assume the existence of two different kinds of grains, each characterized by a different radius. Relative velocities between grains and charge fluctuations are neglected. In order to derive the dispersion relation of this system, we use the well known hybrid fluid-kinetic model, in which ions are treated kinetically and other species as fluids. In this plasma, waves with non-relative velocities between species leads to damped waves with frequency modes, defined by the grain radius. The induced damping ratio is studied as a function of the grain and ion densities.
