    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.

    Operator method analysis of pulse-forming lines and screening
    (2018) Chumakov, V. I.; Kharchenko, O. I.
    In this paper the results of the operator method application to the analysis of processes in the pulse- forming lines and the process of the electromagnetic field screening are presented. The model is considered as a system of Laplace transformed telegrapher’s equations and examples of its solution by the Fourier method and the method of traveling waves (d'Alembert method) are given. Wide perspectives the operator method has for solving problems of analysis of transient in linear devices and systems. The advantages of the operator method are shown, which makes it possible to simplify the analysis. It is shown also that the initial conditions of the problem are taken into account automatically. Examples of the solution of the charging problem of the forming line from the DC voltage source are considered and a comparative analysis of the results obtained by both methods is carried out. It is shown that the solution by the Fourier method allows obtaining an expression for the voltage in the line in the form of a spectral function and may be used at the frequency domain analysis. It was thus obtained that, when the line is charged, the expansion of the function in a series contains only odd harmonics. The solution is given by the d'Alembert method in the form of traveling waves. This result may be used for the time domain analysis. The overlapping of traveling waves leads to overvoltage in the line and the possibility of breakdown of dielectrics between the busducts. An example is given of calculating the screening gate, in which the action of the screen is simulated using a line with distributed parameters Distribution of electric fields is considered. Lattice diagram of the waves is shown to allow explaining process of forming interference pattern in media around the screen and into the screen

    The plasma sources of electromagnetic radiation possess the high electrical indexes (exponent) of efficiency. It’s well known that the radiation power, density and temperature of plasma in such sources depend on the power put in(inserted in, into) a discharge and therefore on a discharge current [1-5]. Space distribution of the temperature research in the field of discharge allow to optimize parameters of power-plant and construction of radiator for maximum (the highest possible) radiation efficiency obtaining.
