Theoretical studies of dusty plasmas have been performed by focusing attention principally on collective phenomena and on grain motion. This thesis consists of a collection of seven published papers that explore both the collective behavior of a complex plasma system as well as the dynamics of grains in plasmas. In paper 1, a mechanism that explains the energy gain which leads to the self excit...

Effects of a uniform magnetic field, the plasma inhomogeneity, and dust charge fluctuations on low-frequency dust-lower-hybrid drift waves have been investigated. Charging currents of electrons and ions to a spherical dust grain in a nonuniform magnetized dusty plasma have been calculated to study the charge fluctuation induced damping or growth of low-frequency drift waves. It is found that fo...

This paper provides an overview of modern research on magnetoplasma methods influencing gas-dynamic and plasma flows. The main physical mechanisms that control the interaction discharges with gaseous moving media are indicated. ways organizing pulsed energy input, characteristic aerodynamics, briefly described: linearly stabilized discharge, compressor, capillary laser-microwave action, electro...
