Abstract
A theoretical investigation has been made of an obliquely propagating low-frequency electrostatic dust-convective cell mode in a nonuniform dusty magnetoplasma, taking account of both the unbounded and bounded plasma situations. It has been shown that for (kd/k)2≫ωcd/ωci, where kd is the inverse of the dust density inhomogeneity scalelength, k is the wave number, and ωcd (ωci) is the gyrofrequency of the dust particle (ion), there exists a new drift-like dust-convective cell mode characterized by the frequency ω≃ωcdk/kd (when the density gradient is positive) or ω≃ωci|kd|/k (when the density gradient is negative). The dispersion properties of the obliquely propagating dust-convective cell mode as well as our newly found mode are found to be significantly modified by the effects of finite cylindrical/slab boundaries. The implications of our results in both space and laboratory dusty plasma environments are briefly discussed.
