    Design of radiation of elektron-beams antenna
    (2010) Lonin, Yu. F.; Stolуrchuk, A.V.; Zvyagintsen, A. Yu.; Chumakov, V. I.; Ponоmarev, A. G.
    Theoretical and experimental studies indicate the possib ility of generating pulses with a relatively wide range, due to excitation of high-current electron beam antennas (EBA). Experimentally investigated isolated rod and heli- cal antennas. The possibility of UWB radiation with high intensity of the far field. The results of modeling a conical spiral EPA excited her pulse currents of various forms

    Genertion UWB signal at energization of a helical antenna hige-current reb
    (2006) Chumakov, V. I.; Balakirev, V. A.; Gorban, A. M.; Egorov, A. M.; Kantemirov, A. V.; Lonin, Yu. F.
    In operation the possibility of generation of UWB signal was researched at excitement of a helical antenna by a high-current relativistic bundle of nanosecond duration. The experiments were conducted on a high-current relativistic accelerator REB "Темр-А" with parameters: Eb ~ 0,5 .1,0 МeV, Ib ~ 5 -10 кА, duration of a ~15nс., at the value of a leading edge ~ 1...2 nс. The calculation data of a helical antenna and parameters of a generated UWB signal are reduced

    On analysis of the elektromagnetic resistance of radioelektronic devices under impulse radiation
    (NSC KhIPT, 2018) Lonin, Yu. F.; Ponomaryov, A. G.; Chumakov, V. I.
    The results of investigations on degradation effects in the radioelectronics circuit ryunder the influence of the high-intensity pulse radiation are given. Analysis of the mechanism of degradation because of hortening the radio pulse radiation wave length has been carried out .When the wavelength of the object, exposed to the radiation of a centimeter range, exceeds the characteristic size of structural elements, the degradation mechanism is conditioned by the quasi-static effects on the object structureinhomogeneities . The degradation effects manifest themselves in a c-cordance with the concept of a "weak link" and localization damage model . In the case of wavelength shortening, when the characteristic size of the objectstructure elementbecomes commensurable with the wavelength, the resonance effectaction is more and more increasing. The degradation redistribution occurs according to the field intensity distribution in the resonantregions. The problem of electromagnetic resistance lowering, under conditions of the tendency towards the radio electronics circuitry microminiaturization, is discussed.

    Simulation of the thermal mechanizm in semiconductors under action of pulsed electromagnetic field
    (2004) Chumakov, V. I.; Slipchenko, N. I.; Stolarhuk, A. V.; Egorov, A. M.; Lonin, Yu. F.
    The paper presents a model taking into account the time character of heat localization and distribution in semiconductor devices unlike the classical Wunsch-Bell linear model describing the thermal mechanism of EM-radiation action on REA. The classification of action levels is given. The nonlinear model permitting to determine the time boundary of heat propagation in the semiconductor device is presented. In the time range t>tcr a uniform volumetric heating of the object takes place, and for t
