Preserved Fulltext
Propagation of dust ion acoustic waves in plasmas composed of non-thermal distributed electrons and stationary dust particles is investigated. Nonlinear Schrdinger equation is derived to describe small amplitude waves, using the reduction perturbation technique. Modulation instability of dust ion acoustic waves is analysed for this system. Parametric investigation indicates that growth rate of the modulational instability is sensitive to the value of non-thermal parameter and relative density of plasma constituents.
