Propagation of arbitrary amplitude dust-ion acoustic waves in the collisional magnetized dusty plasma in the presence of non-thermal electrons

Abstract

Using the Sagdeev pseudo-potential method, the oblique propagation of dust-ion acoustic solitary waves is studied in a magnetized dusty plasma. By considering non-thermal distribution of electrons, the related pseudo-potential is obtained using the Poisson equation. The behavior of the wave is investigated for some ranges of parameters. It is demonstrated that the increase in ion density, lz, β, and also δ1 can lead to the increases in the width and amplitude of the pseudo-potential, while any increase of a2, the coefficient that describes the first nonlinear term in the G(ϕ), increases the amplitude of the V(ϕ).

Nonlinear propagation of fast and slow magnetosonic waves in collisional plasmas

“…[13] Nonlinear electrostatic and electromagnetic waves have been studied in the presence of different collision phenomenon. [14][15][16][17][18][19][20][21][22][23][24][25][26][27] Nonlinear dust magnetosonic waves with inertia-less ions and electrons in the presence of dust-ion and dust-electron collisions have been studied and was shown that the magnetized, collisional dusty medium can be described by the modified Korteweg-de Vries (mKdV) equation.
