Electrostatic sheath at the boundary of a magnetized dusty plasma

Considering the Boltzmann response of the ions and electrons in plasma dyna mics and inertial dynamics of the dust charged grains embedded in a constan t magnetic field, the nature of the electrostatic potential near a plasma b oundary is investigated. Based on the fluid approximation, the formation, a s well as the characteristic behaviors, of sheath in plasma contaminated wi th dust charged grains is studied. It is expected that the presence of dust charged grains will lead to a very different behavior of the sheath as com pared to that of electron-ion plasma. Moreover, in the presence of an appli ed magnetic field the sheath exhibits novel features. (C) 1999 American Ins titute of Physics. [S1070-664X(99)01109-X].
