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

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 δ 1 can lead to the increases in the width and amplitude of the pseudo-potential, while any increase of a 2, the coefficient that describes the first nonlinear term in the G ( ϕ ) , increases the amplitude of the V ( ϕ ) .
