  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.
