Particle simulation code for charge variable dusty plasmas

Overview & Synopsis

Charges on the dust grains immersed in a plasma vary in time. We follow the hydrodynamic approach to obtain dispersion relations for some low frequency electrostatic modes, taking into account charge fluctuation on the dust. We have used the description of the one dimensional fully electromagnetic particle code. There exists one spatial dimension and three velocity components. This is usually referred to as a model. Our analysis shows that the presence of the dust grains causes different effects in different frequency regimes.
