It has been developed the model that takes into account the relativism of electrons in the neoclassical theory of transfer in fusion plasma; the influence of low-frequency drift oscillations on the evolution of lower-hybrid cavities has been studied; the theory of pulsed dusty Ar and Ar/C2H2 gas discharges has been developed; the waves in structures with plasma and metamaterials have been studied; the model of inductively coupled plasma which takes into account the velocity distribution of ions and electrons stochastic heating has been created; the conditions for the formation of pulsed electron and proton beams in the double layers of high-current pulsed low-pressure diodes with metal hydride hydrogen plasma injectors and the conditions for stabilizing the plasma by an external magnetic field have been determined. It has been determined that forced cooling of metal hydride cathode stabilizes the working pressure and provides local hydrogen supply and allows for discharge operation under the conditions of significantly low pressures, providing controlled hydrogen consumption by current adjusting. It has been shown the possibility of creation a neutral hydrogen injector, where the quantity and the rate of hydrogen front expansion are regulated by the pulses of discharge current of different duration. It has been shown that in the high-current plasma diode under the conditions of an independent plasma-beam discharge appearing it is possible to introduce local pulse power over 100 MW at initial energy up to 200 J. It has been determined the effective ways of the location area and the parameters of the double layer control together with the increase in the efficiency of discharge energy input. It has been created the theoretical model of nonstationary double layer in the plasma of high-current pulsed discharge, which takes into account the capacitive component of the current. It has been investigated the spatial dynamics of plasma which is radiated in the range of vac
