Abstract: In this paper, the problem of sheath is investigated using the fluid model in a magnetized four-component dusty plasma system comprising positive ions, variable charge of the dust grains and two species of electron populations with two different temperatures, low temperature electrons (LTEs) and high temperature electrons (HTEs). Both electrons are assumed to be a sum of two superthermal electrons which are related at superextensive electrons distribution. The effects of temperature ratio of HTE to LTE superextensive electrons on the plasma sheath parameters are studied numerically. A significant modification is observed in the quantities characterizing the sheath as sheath thickness, sheath potential and dust velocity in the presence of the two groups of superthermal electrons.
