Lower hybrid drift instability in dusty plasmas

Using kinetic theory, the lower hybrid drift instability is investigated in a dusty plasma In our model, for the length and time scales of the fluctuations the electrons are treated as magnetized, while the ions and the dust species (negatively charged) are unmagnetized The instability is driven by the equilibrium diamagnetic current associated with the electrons and ions. The dependence of the real frequency and growth rate of the lower hybrid drift instability on plasma parameters such as particle drift speeds, densities and temperatures dust to ion mass ratio and dust charge, is studied.
