Karazin Kharkiv National University popup.description2  It was determined that irradiation of the metal hydride with an electron flux from the primary plasma stimulates the release of hydrogen and the formation of a denser transient plasma above the metal hydride surface. A strong mutual influence between the electron current and the transient plasma generation was found. It is shown that the formation of a shielding transient plasma on desorbed hydrogen occurs at temperatures significantly lower than the melting point of the sample. The relativistic generalization of the Taguchi method is proposed. A closure of the system of relativistic neoclassical transport equations is obtained, the solution of which allows determining both parallel and radial flows of particles and heat, taking into account the contributions of radial gradients to the parallel current ("bootstrap" current) as well as the contributions of parallel currents to radial fluxes. The model of an axisymmetric tokamak with a D-shaped profile of magnetic surfaces has been developed. The drift-kinetic equation for the perturbed distribution functions of plasma particles is obtained, taking into account the effects associated with their magnetic drift and the finite width of their banana trajectory. The influence of drift effects on the trajectories of untrapped and trapped particles in axisymmetric tokamaks is determined. The temporal dynamics of the evolution of plasma electron concentration cavities in the Earth's ionosphere is determined, which is caused by nonuniform stochastic electric fields from the moment of the cavity formation to the establishment of a stationary state. The transformation of symmetric and antisymmetric surface electromagnetic TE waves into a single-wave process is investigated. The reflection and refraction of the surface electromagnetic waves of TE polarization at an nonuniform metasurface are investigated. The existence of the effect of total internal reflection for the surface electromagnetic waves with TE-polarization propag Product Description popup.authors Galajdych Viktor K Hrechko Yaroslav O Grishanov Mykola I.
