A microstrip band-pass filter design with two identical L-shaped resonators was studied. Signal injection and signal release is performed by using microstrip transmission lines located on the substrate, on the opposite side from the resonators. Using 3D electrodynamic modeling software, we designed a band-pass filter on a substrate with dielectric permittivity ε=2.5 and thickness h= 1.5 mm. The center frequency of the filter is 1300 MHz, and the operating frequency band is 76 MHz. The design proposed has a compact size and occupies only 50×40 = 2000 mm2. The designed filter and optimized for the necessary parameters, such as minimum bandwidth loss and best matching - can be realized using traditional PCB manufacturing methods, since it has fully technologically realizable dimensions.

In the work, an ordinary microstrip line was studied in order to obtain a compact antenna that can be used as an RFID. So using different cutouts on the radiating antenna strip, it is possible to lower its resonance frequency. In the process, the effect of square cuts and notches on the two opposite ends of the antenna was investigated. Electrodynamic analysis of the proposed antennas, showed that it is possible using simple cutouts, to significantly reduce the dimensions of the antennas. The larger the cut-out area, the more the resonance frequency decreases and, together with it, the dimensions of the antennas. Various cut-outs of a microscatter square radiator were investigated. The entire modeling process was implemented in Ansys HFSS.

Resources of magnetophotonic nanostructures, able to apply in the low temperature environment, are considered. Investigations implemented by authors have demonstrated that, in association with applied photonic or magnetic substances, their nanocrystal structure and disposition (1 D, 2D or 3D structure), application technology, etc., it is very likely that the ferromagnetic nanostructures can be making, that are able to work steady in the extremal conditions of Arctic and Antarctic regions, Near Space, and Solar System planets - at presence of low temperatures and strong influence of ionized radiation. Concentration of impurities, their distribution within magnetophotonic nanocrystal structure and many other factors are very important at subTHz and THz devices of new generation creation. Ferromagnetic and nanophotonic structures opportunities joint application is able to unclose the wide potential for magnetophotonic nanostructures making, in which the ferromagnetics will found the wide application: ferrite-garnets, orthoferrites, various spinel materials and metal amorphous thin films.

One of the tasks in autonomous vehicle control systems is to determine camera angles based on analysis of video stream captured during motion. Assuming that the car is moving rectilinearly along horizontal plane then speed vector of the car in projection onto plane of camera image gives the focus of expansion (FOE). Thereby, search of FOE allows to find two of three attachment parameters (pitch and yaw) and rotation around FOE determines third parameter (roll). In this paper, method of real-time FOE calculation is considered. Speed increasing of FOE calculations is achieved by video binarization and filtering of the reference points determining the optical flow.

A short review was conducted and technical solutions were proposed to eliminate the disadvantages of existing high-temperature measurement equipment. The ways of solving problems related with the allocation of an informative parameter from a nonlinear polyharmonic signal, its transformation and functional processing are suggested. The results of experimental studies confirming the operability of the proposed measurement system are presented.

The method of a self-testing (m, n)-code checker design based on the use of CLBs is considered. CLBs are supposed to be carried out in the framework of LUT-technology. To design the checker, a special expansion formula is used. The set V of checker faults includes all multiple stuck-at faults occurred at CLB inputs. The number l of code words appearing at the inputs of the checker can be less than the number of all possible code words. It implies that some faults of the self-testing checker connected to the outputs of the self-checking circuit can be undetectable. The paper establishes a property of a subset of code words, which allows us to check if a given subset provides the self-testing property of the checker. The property is used in the developed algorithm for analyzing a subset of code words.
