Effects of dust size distribution on instability of obliquely propagating waves in a magnetized dusty plasma

摘要

In the present paper, the obliquely propagating solitary waves are investigated in a magnetized dusty plasma considering vortexlike ion distribution and dust size distribution. A plane solitary traveling-wave solution propagating at an arbitrary angle to the magnetic field is considered. The growth rate caused by small perturbations of any direction to a solitary traveling waves is studied. The effects of the dust size distribution and perturbations on the growth rate are discussed in detail.
