  • Control of wave interaction processes in plasma 
    Buts, V.O.; Kovalchuk, I.K.; Tolstoluzhsky, O.P.; Zagorodny, A.G. (Вопросы атомной науки и техники, 2021)
    The results of processes investigation of nonlinear interaction of wave in plasma were expounded. First of all the mechanisms of the processes control of three frequencies wave interaction were considered. It was shown ...
  • Dissipative instabilities and superradiation regimes (classic models) 
    Kuklin, V.M.; Poklonskiy, E.V. (Вопросы атомной науки и техники, 2021)
    The generation of an electromagnetic field by oscillators in an open resonator is discussed in a one-dimensional approximation. In this case, the development of the so-called dissipative instability - the dissipative ...
  • Energy losses of a point magnetic dipole due to interaction with a magnetized plasma cylinder 
    Averkov, Yu.O.; Prokopenko, Yu.V.; Shmat’ko, A.A.; Yakovenko, V.M. (Вопросы атомной науки и техники, 2021)
    In this work, the excitation problem of bulk-surface helicons by a point magnetic dipole moving in a vacuum parallel to the element of magnetized solid-state plasma cylinder is theoretically studied. The external magnetic ...
  • Features of weakly nonlinear wave interaction 
    Buts, V.A.; Kovalchuk, I.K.; Tolstoluzhsky, A.P. (Вопросы атомной науки и техники, 2019)
    Regular and stochastic dynamics of three wave interaction and dynamics of cascades of such three wave processes were investigated. It was shown that matrix elements of wave interaction are inversely proportional to square ...
  • Modulation instability in two component Bose-Einstein condensate with relative component motion 
    Ivashin, A.P.; Marinenko, E.D. (Вопросы атомной науки и техники, 2019)
    The development of modulation instability in a spatially homogeneous two-component Bose-Einstein condensate (BEC), in which the interacting components move through each other at a relative speed, is investigated. It is ...
  • On the nature of coherents in the system of oscillators 
    Kuklin, V.M. (Вопросы атомной науки и техники, 2019)
    The paper presents the transition to the regime of induced radiation of a system of oscillators in the classical and the quantum cases. This transition occurs due to synchronization by the integral field of the phases of ...
  • On the transformation of the linear differential equation into a system of the first order equations 
    Ayzatsky, M.I. (Вопросы атомной науки и техники, 2019)
    The generalization of the transformation of the linear differential equation into a system of the first order equations is presented. The proposed transformation gives possibility to get new forms of the N-dimensional ...
  • Oscillatory instability 
    Buts, V.A. (Вопросы атомной науки и техники, 2019)
    The dynamics of the oscillator system is investigated. The conditions under which this dynamics becomes unstable are determined. In particular, it is shown that plasma in constant magnetic field becomes unstable if its ...
  • Quasi-harmonic oscillations in a nonlinear transmission line, resulting from cherenkov synchronism 
    Karelin, S.Y.; Krasovitsky, V.B.; Magda, I.I.; Mukhin, V.S.; Sinitsin, V.G. (Вопросы атомной науки и техники, 2019)
    Experimental data and results of numerical modeling are presented, concerning excitation of microwave oscillations by a wave of pulsed ‘dc’ current (eventually, a shock wave) traveling through a radially non-uniform coaxial ...
  • Resonant spread wave function in parabolic potential 
    Mazmanishvili, А.S. (Вопросы атомной науки и техники, 2019)
    In this paper, we consider the parabolic potential, which as a whole is subject to dipole or quadrupole action (parametric resonance), which periodically changes with time, and the dynamics of the wave function of a particle. ...
  • Separation of electroencephalogram low-frequency components on the basis of the stochastic resonance effect 
    Kharchenko, O.I.; Lonin, Yu.F.; Zabrodina, L.P.; Kartashov, V.M. (Вопросы атомной науки и техники, 2021)
    The paper describes the method for electroencephalogram (EEG) analysis based on the stochastic resonance (SR) effect. The numerical computation has provided the separation of low frequency components that fall within the ...
  • Transformation of the linear difference equation into a system of the first order difference equations 
    Ayzatsky, M.I. (Вопросы атомной науки и техники, 2019)
    The transformation of the N-th-order linear difference equation into a system of the first order difference equations is presented. The proposed transformation opens possibility to obtain new forms of the N-dimensional ...
