Abstract
General dispersion relation of plasma waves in a finite temperature flowing dusty plasma in the presence of an external magnetic field has been examined using the Vlasov– Maxwell system of equations. In the frequency regime between ion and dust cyclotron frequencies, the transverse electromagnetic dust-ion magnetosonic wave mode is found to propagate nearly perpendicular to the external magnetic field, which reduces to the usual magnetosonic wave in the absence of dust. The electrostatic dust-lower-hybrid mode is also recovered propagating nearly perpendicular to the external magnetic field in a finite ion temperature and cold dust plasma, which for the strong ion-Larmor radius effect reduces to the usual dust-acoustic wave driven by the ion pressure.
