Abstract

Recent theoretical work on the excitation of Buneman's instability in inhomogeneous anisotropic dusty plasmas is presented. Plasmas with different temperature regime are considered. The dispersion relation is derived and solved for a 1-D Buneman instability excited in such plasmas. Electron to ion temperature ratio, degree of plasma inhomogeneity and dust grains thermal velocity are found to play a crucial role in the growth and damping of Buneman instability.

Keywords
