Three-Dimensional Wakefields in a Magnetized Dusty Plasma with Streaming Ions

Abstract

Properties of three-dimensional wake potentials around a stationary dust particulate in a plasma with magnetic field-aligned ion flows have been theoretically studied. Numerical and analytical results reveal that the wakefield periodicity along the magnetic field direction is significantly affected (unaffected) for a stronger (weaker) magnetic field, while the periodicity in the perpendicular plane is unaffected for both high-and low-density plasmas.
