Recently, more and more stringent requirements for frequency response, as well as for weight and size characteristics, are imposed for input filters. Based on this, the designs of bandpass filters with capacitive and mixed couplings on corrugated waveguides are considered. Possible implementations of such filters on structures with and without symmetry of the electric field are presented. It is shown that for such filters it is possible to increase the slope of the performance below the passband. For filters with mixed (capacitive and inductive) couplings, the slope of the characteristic can be increased both below the passband and above. It is also shown that the implementation of capacitive couplings on stubs of the same cross section significantly increase the steepness below the passband. The possibility of implementing an ultra-compact waveguide bandpass filter with mixed couplings is shown. The frequency responses of the filters are given.

The operation of anomaly detection systems in modern computer networks, as a rule, is associated with the processing of large amounts of traffic. With the increase in the scale of computer networks and the growing complexity of network attacks, it becomes necessary to detect multi-stage attacks in real time. This paper presents the architecture of a multi-stage anomaly detection system. The features of the system are the use of generative adversarial neural networks and the minimization of processed traffic using an attacker’s behavior model. The described architecture has a multilevel structure and allows monitoring in distributed computer networks.

In communications, radar technology, music synthesis, control systems, electronic equipment testing systems, digital generation of harmonic oscillations is widely used. Among the various approaches to solving this problem, the implementation of recursive algorithms for generating samples of sinusoidal signals with a given frequency, amplitude, and initial phase is used. Such oscillators can be represented as IIR digital filters whose transfer function poles are located in the z-plane on a circumference with a radius equal to one. This paper is devoted to the application of the method proposed by the authors used in development of IIR digital filters with a finite bit capacity of coefficients. With this method, poles and zeros are already calculated considering the finite length of the word. These values remain unchanged after the subsequent steps. At these stages, digital filter structures are generated, considering the given accuracy and complexity. In this paper, the generation of structures suitable for the implementation of harmonic oscillators is performed.

The paper presents the schemes for manufacturing a microoptoelectromechanical (MOEM) accelerometer for measuring small accelerations. MOEM-accelerometer includes three subsystems: mechanical, optical and electronic. The mechanical subsystem includes an inertial body, mounted on a spring suspension in a case. The optical subsystem includes a laser, moving and fixed waveguides. The electrical subsystem includes a photodiode and electronic components. To measure microdisplacements that correspond to measured microaccelerations, an optical system based on the optical tunnel effect was used. The work considers the schemes of the optical transducer for linear and angular displacements of the mechanical subsystem. The moving waveguide together with the inertial body are combined into the mechanical sensing element that diverges in the case of acceleration. A technological process for manufacturing a MOEM accelerometer based on the “silicon on insulator” technology with additional layers of nitride and silicon oxide for optical functional elements is presented. Depending on the character of the movement of the sensing element, the functional schemes of the MOEM-accelerometer were developed with various changeable parameters: optical coupling length, gap, overlapping area between the moving and fixed waveguides. The article analyzes the advantages and drawbacks of the proposed schemes of accelerometers from the perspective of their manufacturing feasibility and the predicted accuracy. The highest sensitivity $(6.25 times10^{6} text{m} ^{text{-1}}$) belongs to schemes with changeable gap between the waveguides. The dynamic displacement ranges of them is ± 80 nm. Lower sensitivity $(1.25 times10^{6} text{m} ^{text{-1}}$) belongs to schemes with changeable overlapping area. The dynamic displacement range may reach ± 300 nm. Schemes with changeable optical coupling length possess the highest dynamic range which directly depends on a chosen optical coupling length and amounts to dozens of microns. The sensitivity of the last scheme also depends on the optical coupling length and amounts to $11.25 times10^{3} text{m}^{-1}$ for an optical coupling length of 44 $mu$m and to $30 times10^{3} text{m} ^{-1}$ for an optical coupling length of 15 $mu $m.

The article describes an approach to reversible compression of measurement data frames. It is based on the representation of the bit-difference type of frames as a truth table of some logical function of several variables, with its subsequent minimization. Based on this approach, a reversible compression algorithm has been developed that allows one to switch from direct data compression to encoding the minimal disjunctive normal form obtained in the process of minimization using adaptive prefix coding. The efficiency of the algorithm was studied on data obtained from a number of energy facilities in the Far East. Which showed that this approach to reversible data compression turned out to be quite effective, regardless of their statistical properties and, in particular, stationarity.

The GPR method is being used more and more widely in diagnostics, engineering surveys and inspection of highways, as well as in quality control of road construction works. In this case, different designs of ground penetrating radar and methods of work, as well as various software are used. The ground penetrating radar method is uncontested, since it allows you to continuously explore the internal structure of the pavement structure. This article presents the design of the existing ground penetrating radar and the method of processing the received geodata using this ground penetrating radar.

The results of an experimental study of modules based on strip lines with two layers of dielectric media have been presented in the work. The first layer is a substrate of an FR4 foil material, and the second layer is a bulk lithium niobate crystal. The frequency characteristics of modules made based on three types of strip structures in the form of a coplanar line with a grounded base, SIW-type strip line, and an asymmetrical strip line with a perforated substrate were measured. The lithium niobate crystal was 24×18×39 mm. The crystal was placed on the surface of the strip lines on the side of the current-carrying strip on the XZ plane. The measurements were taken under the influence of an LFM signal in the ultra-wide frequency band ranging from 10 MHz to 26 GHz, as well as when a pulse in the form of a step was applied to the input of the modules. The emergence of microwave quasi-chaotic oscillations in the modules based on the strip lines of three different designs was detected. The effect wasobserved both under the influence of an LFM signal and in the pulse exposure mode. The experimental results show the possibility of constructing devices to form quasi-chaotic signals in the microwave range with characteristics that depend on the type of the strip line structure.

The article presents the results of the development of two ultra-wideband traveling wave amplifiers. These monolithic microwave integrated circuits (MMICs) were developed using gallium arsenide (GaAs) pseudomorphic high electron mobility transistor (pHEMT) technology. One was designed based on a 0.25 $mu$m GaAs pHEMT process with gain up to 30 GHz, and the other based on a 0.1 $mu$m GaAs pHEMT process up to 50 GHz. The measured S-parameters for the first MMIC show a gain (S21) of 15±1.5dB in the frequency range 0-30 GHz, input and output return loss (S11, S22) less than -11dB. The measured S-parameters for the second MMIC show a gain of more than 11.5 dB in the frequency range of 0-50 GHz, input and output return loss of less than -9dB.
