The Excitation of the Low-Frequency Electromagnetic Wave in Dusty Plasma with Vortex Flows

摘要

The Excitation of Alfven wave in dusty plasma with vortex flows is investigated.Thecoupled equations for density and electromagnetic potential of dusty plasma with vortex-flow wereobtained.The stability and amplitude behavior were studied both analytically and numerically.Using a non-modal method,it was found that the presence of dust can suppress the growth of theinstability which can also be affected by the vortex eccentricity.
