Drift wave in the presence of a time varying inhomogeneous electric field

Abstract

The drift instability has been studied in the presence of an inhomogeneous time varying electric field directed perpendicular to the impressed magnetic field in the presence of a magnetic field, and density and temperature gradients, using nonlinear particle trajectories in the Maxwell–Boltzmann–Vlasov equations. The dispersion relation and growth rate have been evaluated for the drift wave propagating obliquely to the magnetic field in a plane normal to a density gradient. The stabilization/destabilization of the drift wave by the inhomogeneous applied electric field has been discussed. The application of these results has been suggested for space plasma.
