Abstract
A drift wave is a prominent mode of a magnetized plasma of inhomogeneous density. It plays an important role in the transport of particles, energy, and momentum perpendicular to the ambient magnetic field. The frequency of this mode is governed by the inhomogeneity scale length and is much lower than the typical homogeneous plasma modes involving ions and electrons. In this work, the possibility of coupling of this particular mode with the low frequency modes of a dusty plasma medium is considered. The drift wave has been found to saturate at large ky (perpendicular wavenumber) in a magnetized plasma with weakly correlated dust species mainly due to the shielding by polarization drift of ions. However, when dust particles are strongly correlated, the drift wave converts into a transverse shear wave at large ky.
