Abstract—The ponderomotive force acting on a variable-charge granule in a dusty plasma from an intense ion–
sound wave is considered. Allowance for oscillations of the granule charge in the field of an ion–sound wave
makes it possible to reveal new components of this force that are proportional to the wave vector of the field
and the cube of its amplitude. These components do not vanish in the case of a uniform field and also lead to a
directed transport of the dust plasma fraction.
