Propagation of Ion-Acoustic Wave in an Inhomogeneous Dusty Plasma with Dust Charge Fluctuation
-
Abstract
The propagation of dust ion-acoustic wave in an inhomogeneous dusty plasma is studied by taking the dust charge fluctuation and collisions into account. It is shown that the dust charge fluctuation brings a phase shift to the wave. Furthermore, because of the presence of dust charge fluctuation, a new damping term rises, which makes the damping more sharply.
