The collisionless magnetized complex plasma (MCP) is considered to describe the nonlinear oblique propagation of dust-ion acoustic (DIA) shock wave and oscillatory having periodicity due impact parameters. Such composed dynamic ions viscous influence, (α, q)-velocity distributed electrons, static positive or negative dust charged particles. By implementing only expansion perturb quantities, Bur...

In the sheath region, the ion flow to the electrode provides a distinctive direction, with the plasma properties different in the direction parallel or perpendicular to the flow. The ion flow is responsible for the generation of the wake potential for a test dust particle, which in the linear approximation is within the Mach cone for supersonic ion velocities. The bottom dust particle appearing...

The dynamics of the shielding of particulates (“dust”) in low pressure glow discharges have been investigated with a pseudoparticle-in-cell simulation for electrons and ions in the vicinity of a dust particle. The potential of the dust particle, and the orbital nature of ions around the dust particle, depend on the collisionality of the ions. Collisions of orbiting ions effectively increase the...

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...

The propagation dynamics of the nucleus-acoustic waves (NAW) in a quantum plasma composed nondegenerate inertial light nuclei, stationary heavy and ultra-relativistically degenerate electrons positrons has been theoretically investigated within framework Boussinesq equation, which is valid for bi-directional small but finite amplitude limit. N-soliton solution equation derived using Hirota's me...

By orbit-limited motion (OLM) theory and the kinetic model, currents carried by electronsand ions on the dust grain are obtained and the effects of temperature and drift velocity of ions on thedust grain electrical potential are considered. The calculations were performed for finding the role of densities of dust grains and ions on the dust grain electrical potential which is the ma...

A dusty plasma system containing Boltzmann-distributed electrons, non-thermal ions, and mobile charge fluctuating negative dust has been considered. The nonlinear propagation of the dust-acoustic (DA) waves in such a dusty plasma has been investigated by employing the reductive perturbation method. It has been found that the dust charge fluctuation is a source of dissipation, and is responsible...

An experimental investigation of dust acoustic ~DA! waves in a dc glow discharge plasma is described. The glow discharge is formed between a 3 cm anode disk and the grounded walls of a 60 cm diameter vacuum chamber which is filled with nitrogen gas at a pressure of about 100 mTorr. Dust located on a tray in the chamber is attracted into the plasma where it is trapped electrostatically. The dust...
