Low frequency electrostatic waves in a cylindrically bounded dusty magnetoplasma with nonadiabatic dust charge fluctuation

摘要

A rigorous theoretical investigation is made for the low frequency electrostatic waves in a cylindrically bounded magnetized dusty plasmas with nonadiabatic dust charge variation, and the dispersion relation for the low frequency modes is derived. The combined effects of the cylindrical boundary, the external magnetized field, the nonadiabatic dust charge fluctuation, the nonthermally distributed ions and the ratio of electron to ion density on the low frequency waves are studied in great detail. It is shown that the mentioned effects have a strong influence on the dispersion properties of the low frequency modes. (C) 2007 American Institute of Physics.
