Nonplanar double layers in plasmas with opposite polarity dust
A. A. Mamun, A. Mannan Department of Physics, Jahangirnagar University
Abstract:
Nonplanar (cylindrical and spherical) double layers (DLs) in a
four-component dusty plasma (composed of inertial positively and
negatively charged dust, Boltzmann electrons and ions) are
studied by employing the reductive perturbation method. The
modified Gardner (mG) equation describing the nonlinear
propagation of the dust-acoustic (DA) waves is derived, and its
nonplanar double layer solutions are numerically analyzed. The
parametric regimes for the existence of the DLs, which are found
to be associated with positive potential only, are obtained. The
basic features of nonplanar DA DLs, which are found to be
different from planar ones, are also identified. The implications
of our results to different space and laboratory dusty plasma
situations, where opposite polarity dust are observed, are
discussed.
