In this work, a damped modified Kawahara equation (mKE) with cubic nonlinearity and two dispersion terms including the third- fifth-order derivatives is analyzed. We employ an effective semi-analytical method to achieve goal set for study. For purpose, ansatz implemented find some approximate solutions mKE. Based on proposed method, different formulas analytical symmetric approximations are for...

By adjusting the anode current and axial magnetic strength of a dc-glow-discharge dusty plasma, we have found plasma and dust conditions conducive to dusty plasma structurization, similar to the one discussed theoretically by Morfill and Tsytovich [Plasma Phys. Rep. 26, 682 (2000)]. The structurization instability leads to the formation of a pattern where the dust suspension transforms into alt...

We report theoretical and experimental results on the radiation pattern of the ion acoustic waves below the ion cyclotron frequency from a small probe in a streaming magnetoplasma. In the fluid approximation with cold ions the ion acoustic resonance cones are found to be drastically changed. Experimental ray velocities and constant phase surfaces are in good agreement with the theoretical results.

The nonlinear propagation of different types DANW acoustic dust waves has been investigated in a magnetized dusty plasma consisting negatively charged particles, Maxwellian electrons, and ions. Application the standard reductive perturbation theory is used to derive corresponding three-dimensional complex Ginzburg–Landau (3D-CGLE) equation which governs dynamics dust-acoustic wave packets. stat...

A comparative analysis of the most important dissipative processes occurring during the excitation and propagation of dust ion-acoustic shocks in a Q machine device, among which are the charging of dust grains, the absorption of ions by grains, the transfer of the ion momentum to the grains, and Landau damping, is performed. The relative roles played by dissipative processes in different types ...

Effects of dust-neutral collision and densities of positive ions and electrons have been investigated for the propagation of dust-acoustic waves ~DAWs! in magnetized dusty plasmas. It is found that, due to collisions, the DAWs damp waves and the damping rate of the waves depends mainly on the collision frequency ~i.e., if there are no collisions the waves do not damp waves!. The collisions are ...
