摘要

A new type of very low-frequency electrostatic wave in a dusty plasma, called the dust-drift wave, has been investigated with the three-component fluid model. The dispersion of the waves depends strongly on the dust grain content in plasma. Due to their nonlinear interaction, the dust-drift waves can form two-dimensional diphump and multi-peak localized structures. The amplitudes of those structures decrease with the increasing dust content.
