Analytical Solitary Wave Solution of the Dust Ion Acoustic Waves for the Damped Forced Korteweg-de Vries Equation in Superthermal Plasmas

Analytical solitary wave solution of the dust ion acoustic (DIA) waves was studied in the framework of the damped forced Korteweg-de Vries (DFKdV) equation in superthermal collisional dusty plasmas. The reductive perturbation technique was applied to derive the DKdV equation. It is observed that both the rarefactive and compressive solitary wave solutions are possible for this plasma model. The effects of. and the strength (f(0)) and frequency (omega) of the external periodic force were studied on the analytical solitary wave solution of the DIA waves. It is observed that the parameters k, f(0) and. have significant effects on the structure of the damped forced DIA solitary waves. The results of this study may have relevance in laboratory plasmas as well as in space plasmas.
