Abstract :
The propagation of arbitrary
amplitude dust ion acoustic waves (DIAWs) in a
magnetized collisional dusty plasma including
hot electrons, with kappa velocity distribution
for electrons, warm ions and dust particles has
been studied. In the presence of immobile
massive dust particulates, DIAWs have been
investigated through the Sagdeev pseudopotential
method. It is demonstrated that the
amplitude and width of the pseudo-potential are
increased with the ion density and also with
Directional cosines. It is shown that the
behaviors of the amplitude and the width of the
wave in terms of all of plasma parameters is
similar to the our recently work, and the
spectral index has a little effect on the wave.
