The linear dispersion relation of the electrostatic waves in magnetized anisotropic dysty plasma

The linear and weakly nonlinear dust-ion-acoustic wave propagation obliquely with respect to an external magnetic field is studied in magnetized dusty plasma, which consists of magnetized fluid ions bearing with anisotropic pressure, suprathermal electrons, and static dust grains. In the linear regime, the magnetized dusty plasma supports the propagation of fast dust-ion-cyclotron (EDIC) mode and the slow electrostatic dust-ion-acoustic (DIA) mode.
