Study of dust ion-acoustic wave propagation in the Lorentzian magnetized dusty plasma

• Dust ion-acoustic waves propagation in the magnetized dusty plasma studied using kinetic equation.
• In the presence of magnetic field, the dielectric tensor components calculated in case the parallel propagation.
• It is shown that the Landau damping effect vanishes for parallel propagation.

Dust ion-acoustic waves propagation in the magnetized dusty plasma including ions, electrons and dust particulates are studied by using kinetic equation. For unbounded and collisionless plasma and in the presence of uniform external magnetic field B0, electrons and ions with Lorentzian distribution function and dust particles with Maxwellian one are considered. Calculating dielectric tensor through the Vlasov equation solution, in the parallel propagation, dispersion relation is derived and suprathermal particle effects on the Landau damping is studied. It is shown that the Landau damping effect vanishes for parallel propagation.
