Propagation of Nonlinear Dust-Acoustic Waves in a Self-Gravitating Collision Magnetized Dusty Plasma in Earth’s Magnetosphere

Abstract

The nonlinear propagation of different types of DANW acoustic dust nonlinear waves has been investigated in a magnetized dusty plasma consisting of negatively charged dust particles, Maxwellian electrons, and ions. Application of the standard reductive perturbation theory is used to derive the corresponding three-dimensional nonlinear a complex Ginzburg–Landau (3D-CGLE) equation which governs the dynamics of the dust-acoustic wave packets. The stationary analytical solutions of the CGLE are numerically analysed where the effect of the physical parameters of the dusty plasma model on the wave’s propagation is taken into account. It has been found that there can be a relationship between the appearance of soliton waves and electromagnetic waves, as well as between shock-like waves and periodic travelling waves. Expression of the importance of these findings is the cornerstone of explaining the true relationship between the propagation of nonlinear waves in the physics of space, for example, the Earth’s magnetic field.

The multi-peak point phenomenon of broadband microwave reflection caused by inhomogeneous plasma

“…In previous flight experiments, the spatial distribution of electron density could not be precisely measured, and only the electron density at specific points could be obtained. The improved scattering-matrix method (ISMM) has been effectively used to simulate the propagation of terahertz waves in inhomogeneous plasma, addressing the singularity issue prevalent in the traditional scattering-matrix method [13]. The study of the effects of physical parameters on wave propagation in magnetized dusty plasma models can be conducted using the three-dimensional nonlinear complex Ginzburg-Landau (3D-CGL) equation [14].…”
