The study of lenses when their sizes are units and tens of wavelengths. For the analysis of lenses in the specified range, it is proposed to use a high-frequency integral equation with the representation of the green function in both spherical and cylindrical representations. The focusing properties of lenses of different profiles are investigated.

In the paper, radiation characteristics of the conformal ferrite loop magnetic antenna (MA) are investigated using HFSS. The antenna is set in a superstructure of the surface ship (SS) and is intended for a long-distance radio communication in the range of 10-30 MHz. The antenna power is four single-turn windings with ports on multilayered ferrite cores of a loop. Effect of the phase feeding of the ports on the directional properties and efficiency of the antenna was studied taking into account the electromagnetic interaction with the SS body and the underlying surface. The radiation patterns in the main planes and the values of the efficiency of the MA-SS system at frequencies of 10-30 MHz for different modes of antenna power are presented.

This paper presents the method of calculating the maximum usable frequency (MUF) and field strength of radio waves reflecting 2 times at the F2 ionosphere layer under inhomogeneous conditions of the ionosphere. The comparison between predicted and measured MUF has shown that the proposed method significantly increases the accuracy of calculation MUF. The results of calculating frequency dependence of the radio field strength have shown that the scattering of radio waves in the ionosphere leads to the possibility of receiving radio waves at frequencies exceeding the maximum usable frequencies.

The relevance of the development and modernization of synchronization algorithms, which reduce the synchronization time of the quantum key distribution (QKD) system, while maintaining enhanced security against unauthorized access, is noted. The synchronization algorithm is described, where, to increase security from unauthorized access, quantum pulses are used as synchronizing signals. A quantitative assessment of the influence of the dispersion properties of a fiber-optic line on the efficiency of the two-stage single-photon synchronization algorithm of the autocompensation QKD system is given.

An amplitude-phase distribution of the field in the aperture of a linear antenna array which ensures the formation of frequency-independent radiation characteristics in a wide frequency band has been proposed. For this distribution, a representation of the radiation pattern is obtained in the form of a sum of partial diagrams corresponding to the components of the amplitude aperture distribution. The main relations of the frequency-independent radiation pattern formation were analyzed. In particular, the dependence of the maximum permissible inter-element antenna array distance on the relative frequency overlap and width of the generated radiation patterns has been established.

A model of calculation of polarization scattering matrices for objects of observation in a complete polarization basis in view of features of their motion was developed. Simulation of implementations of polarization scattering matrices for various classes of objects of observation was carried out. Plots of dependence of the angle between the symmetry axis of objects of observation and the sight line on the time of observation were presented. Simulation of the process of classification of objects of observation by polarization attributes with the use of the model of calculation of polarization scattering matrices was carried out. Based on obtained implementations of polarization scattering matrices, informativeness of various groups of polarization attributes was studied.

The article describes the method and process of designing a interdigital bandpass filter on two two-stage microstrip resonators. As a result of the design, thanks to the introduction of two steps of different widths into the resonator, it was possible to double the barrier band by suppressing the parasitic bandwidth in the vicinity of the third harmonic.
