The paper presents a semi-analytical method for calculating the shielding effectiveness (SE) of an enclosure with an aperture filled with a dielectric or magnetic material. The method is based on a combination of quasi-static analysis of coplanar strip lines (CPS) and an analytical model of an enclosure equivalent circuit. A simulation of a CPS is reduced to solving a simple electrostatic problem and can be performed by any available numerical method. The SE calculation can be performed using any of the existing models of an enclosure equivalent circuit. In the range up to 1 GHz, a validation of the proposed method was carried out using a standardized enclosure 300×120×300 mm3 as an example. To show the capabilities of the method, the paper presents the results of SE for enclosures with a PVC ventilation grill and a glass in the aperture. Using this method in conjunction with a previously published analytical model, the SE calculations for the enclosure with a conducting plate were also performed. The results show that the proposed method has an acceptable accuracy, and the average value of the absolute error does not exceed 6.4 dB
本文提出了一种半解析法，用于计算电介质或磁性材料填充孔径的外壳的屏蔽效能。该方法结合了共面带状线的准静态分析和外壳等效电路的解析模型。CPS的模拟被简化为解决一个简单的静电问题，并且可以用任何可用的数值方法来执行。SE计算可以使用任何现有的外壳等效电路模型来执行。在高达1 GHz的范围内，以标准化外壳300×120×300 mm3为例对所提出的方法进行了验证。为了展示该方法的能力，本文给出了带有PVC通风格栅和孔径中有玻璃的外壳的SE结果。利用该方法与先前发表的分析模型相结合，还对带有导电板的外壳进行了SE计算。结果表明，该方法具有可接受的精度，绝对误差的平均值不超过6.4 dB

The article presents a description of a hybrid algorithm for generating fuzzy rules for a fuzzy classifier using grasshopper optimization algorithm and the K-means data clustering algorithm. The performance of clustering was evaluated by three fitness functions: total variance, Davis–Bouldin index, and Calinski–Harabasz index. Triangular and Gaussian membership functions have been investigated. The efficiency of the generated fuzzy rule bases has been tested on real datasets. The best combination is to use the total variance as the fitness function and the Gaussian function as the membership function.

Quantum keys created during the quantum key distribution protocol have absolute secrecy due to physical laws and are not susceptible to breaking even with the unlimited computing power of the attacker. However, quantum key distribution systems have a range limit. Quantum key distribution networks based on trusted intermediate nodes are built to overcome the problem of the maximum range. This paper examines the connection of backbone networks with networks of arbitrary topology, introduces criteria for the classification of key generation and distribution schemes, and classifies some schemes according to the criteria introduced.

The algorithm of estimating the bearing in phase direction finders with a flat aerial array is suggested according to a set of differences in signal phases measured between the elements of the aerial system. The aerial system presents two linear lattices located orthogonally. The law of distributing the error probabilities of the phase measurements does not influence the algorithm. The algorithm can be applied for the direction finders equipped with the orthogonal linear lattices having any number of phase-measuring bases.

A method to analyze the non-linear-inertial properties of devices for recording (analog-to-digital conversion) of signals is considered. The method includes a building of a model of a digitizing device in the form of a nonlinear recursive filter of a limited order (second or third). Two or four non-linear functions in such a model are proposed to be considered as characteristics of the non- linearity of the device. The influence of these characteristics on different parts of the transient response of the device is indicated. For the selected example (digital oscilloscope), it is shown that the nonlinearity of the oscilloscope quantizing unit itself has an unsystematic character, but is small against the background of relatively smooth distortions in the analog path of the oscilloscope.
