Effect of nonthermal ions on (3+1)-dimensional envelope solitary wave in magnetized PLD dusty plasma

Abstract

This work investigates the envelope solitary wave (ESW) in magnetized power law distribution dusty plasma consisting of free electrons and nonthermal ions. A (3+1)-dimensional nonlinear Schro¨ dinger equation (NLSE) through the reductive perturbation technique is derived. The nonlinear dispersion relation ω= ω(k) and coefficients of NLSE are analyzed in detail by the numerical simulation method under the effect of nonthermal ions. It is indicated that the frequency increases as the number density of nonthermal ions increase. It can be seen that the frequency with higher unperturbed ion number density is larger than that with lower case. Moreover, the effects of amplitude and width on ESW are discussed with different plasma parameters. The present results can be important in understanding the characteristics of ESW for a magnetized three component plasma system.
