Often apply spread spectrum signals to protection of communication systems against narrow-band hindrances. Protective abilities of a communication system at the same time are defined by the size of base of a spread spectrum signal. If hindrance power too big, isn't enough such protection. In this case additional ways of protection, for example, a rejection of a powerful hindrance are necessary. The present report is devoted to assessment of deterioration in autocorrelated function because of a rejection of a part of a range of a difficult signal together with a hindrance.

Elements of a display are an important part of information systems. Necessary to study parameters of materials and designs. To create new samples of indicators and control the quality. This problem required an integrated approach. Therefore the development of an automated device for testing thin film electroluminescent indicators is an important task as it allows accelerating the search for new materials and structures with necessary parameters. Investigators of Ulyanovsk State Technical University together with scientists from Ulyanovsk State Civil Aviation University investigated the algorithms, methods and devices for measuring parameters of thin film electroluminescent indicators. As a result of the project of the automated device for testing thin film electroluminescent indicators was developed.

Regularities of changes of morphological and field emission characteristics of superficially structured silicon plates of electronic type of conductivity received with use of etching of natural oxides of silicon in fluorocarbon plasma and ion-physical dispersion in argon plasma are investigated. It is shown that superficial structuring with use of carbon subnanodimensional mask coverings allows to receive the set field emission currents at various tensions of external electric fields. In relation to the received field emission structures the physical and chemical model of two-level tunneling of electrons is considered. Scientific interpretation of the mechanism of destruction of the many apex silicon cathodic matrixes received with use of plasma processing in various chemically active gas environments is offered.

The usage of non-standard waveguides, e.g. single or double ridge waveguides, can give us big technical advantages relative to conventional solutions. The bottleneck of using such waveguides is that estimation of the measurement uncertainty is a formidable task. The most popular VNA calibration method TOSM (SOLT) uses match standard, which cannot be characterized by standard approach. The usage of TRL-method is restricted because characteristic impedance and wave propagation constant cannot be directly calculated form the geometry of some non-standard waveguide types. The authors offer LRT-method as an alternative solution for VNA calibration. New method uses minimal calibration kit like the already known TRL-method: electrically long line as match, direct waveguides connection as through, short or open as reflect standard and iterative procedure to calculate 8- or 12- error terms models. Since standard-to-non-standard waveguide adapters are used with serial produced VNAs, authors suggest to estimate uncertainty in reference to results, which were estimated in standard coaxial or rectangular waveguide with TOSM calibration.

Structure of a new type cavity of rectangular shape with a central metallic core is considered. The influence of internal dimensions (core radius) on the eigenfrequencies and the eigenfunctions of electromagnetic field of the two lowest H- and E-modes of such concentric resonator are determined with the help of the finite element method. Moreover parameters of scattering matrix of rectangular concentric resonator with coaxial input and output ports are investigated for the Ka-band. Possibility of realization of small-sized bandpass filter on its basis is shown. Factors influencing on the reflection coefficient in the pass band are analyzed.

This article considers opportunity of the gas-filled neutron tube's ion source modeling by the KARAT code. To increase the efficiency of registration equipment in oil and gas logging, it is necessary to significantly reduce the duration of the neutron pulse front. To verify the adequacy of the numerical model, the experimental oscillograms of the extracted ion current and the discharge current was compared with the oscillograms obtained by simulating the work of gas-filled neutron tube GNT1-32 by the KARAT code under the same conditions. Despite the fact that the experimental oscillograms had a wide spread from pulse to pulse, the comparison showed a satisfactory agreement with the calculated data for such key parameters as the front time and pulse amplitude for both the extracted and the discharge current.

The regularities of the modification of the current-voltage characteristics of MIS structures due to the formation of built-in surface potentials are investigated. Surface potentials are formed when an atomically clean surface of silicon crystals is obtained using microwave plasma microprocessing. Microwave plasma microprocessing was carried out in various chemically active gas media. The interpretation of the effect of surface potentials on transversal electron transport and the steepness of the current-voltage characteristics of silicon MIS devices has been experimentally established and proposed.

The surface and backward volume magnetostatic spin waves propagation in the side-coupled magnonic micro- nanowaveguides was numerically studied. The dispersion characteristics was calculated using the modification of finite element method. The transformation of the frequency dependence of the coupling length with the variation of the geometrical parameters was investigated. The cases of surface and backward volume magnetostatic waves were considered. It was shown that the coupling length is increased in the surface wave geometry. The influence of the external bias magnetic field orientation on the spectra of wave in lateral structures was demonstrated. The neuromorphic network of lateral stripes can be used in the pattern recognition methods.

A solid-state pulse generator for power-supply systems of magnetrons with cold cathodes was developed. The generator, designed for output high-voltage pulses of 15 kV / 0,5 ¼s, uses a pulsed transformer circuit for transferring voltage to the load. The switching unit of the generator is based on the high-voltage semiconductor switches with series-parallel connection of IGBT-transistors. The results of the tests carried out at JSC “RPE «Toriy”» showed the stable operation of generator and the possibility of its using in the pulsed power-supply systems of microwave devices for various applications.
