Kinetic and hydrodynamic modes of propagation in strongly coupled dusty plasma with radiative effects

The polarization force and the charge-gradient force effects in strongly coupled dusty plasma along with the effects of viscosity are studied using theoretical techniques. The strongly coupled dusty medium is suitably described by the simplified phenomenological fluid model. The plasma model is considered to compose of Maxwellian distribution of ions and radiative electrons along with comparatively massive dust grains. With the Generalized Hydrodynamic (GHD) fluid model, the dispersion relation is deduced and the collective properties of the medium are discussed. The viscoelastic and low frequency modes of the waves derived from the dispersion relation and the instabilities of the plasma are inspected in detail to understand the hydrodynamic mode of propagation and the kinetic mode of propagation.
