this article discusses the features of simulation short-pulse ultra-wideband radio communication systems in the organization of communication networks in autonomous groups of unmanned aerial vehicles. The model of the ultra-wideband radio system and factors affecting the parameters of the communication network that arise when constructing a radio network in a mobile unmanned aerial vehicles group (that changes its configuration and altitude during the flight) are considered. The results of modeling such a radio system are presented, the requirements for the radio system and recommendations for its construction are formulated.

A mathematical temperature model of propagation characteristics is presented and its study is performed on the example of a microstrip transmission line. It was found that the maximum change of line characteristics with the separate influence of a temperature change from minus 50°C to 150°C on each of the cross-section parameters of the line does not exceed 1%, and with a simultaneous influence on all parameters 10.76%. It was revealed that the maximum influence on the change of line characteristics is exerted by the change of the substrate relative dielectric permittivity, at which the maximum change in per-unit-length parameters is up to 10%.

Vanadium dioxide VO2 is a promising functional material for many practical applications, due to its large jump in conductivity observed during the phase transition. One of the main tasks for VO2 material is to improve its phase transition characteristics. In this paper, we study the effect of post growth annealing on the phase transition properties in two types of VO2 films synthesized by LP CVD on $mathrm {S}mathrm {i}O_{2}/mathrm {S}mathrm {i}$ substrates: with a low $(< 10)$ and high $(>10^{3})$ resistance ratio during the phase transition. Using layer-by-layer etching, we showed that both types of VO2 films are not uniform in thickness due to the presence of a non-stoichiometric $VO_{2-mathrm {x}}$ layer. The location of this layer determines the experimentally measured value of the jump in the conductivity of VO2 films, as well as the possibility of improving the phase transition characteristics in the films by annealing. As a result, we found annealing conditions that increase the value of the jump in resistance during a phase transition up to 700 times. The results of this work are promising both for using VO2 as the basis for novel electrical and optical micro- and nanodevices, and for studying the physicochemical properties of VO2 films synthesized by CVD.

This paper describes a theoretical study of the effect of amplification of radiation from quantum dots upon resonance excitation of localized surface plasmons in three-dimensional silver nanoislands located on the surface of a Ge/Si heterostructure with quantum dots. It was found that the interaction of the emitters with silver nanoparticles can lead to a significant increase (by more than an order of magnitude) in the yield of radiation from the hybrid structure.

The paper discusses a method of constructing a model of the terrain reflections to land clutter simulation. The basis of this method is the transformation of an array of the initial data calculated using a terrain map into an array with fewer number of elements. The conversion requirements depend on the radar parameters, namely, on the type of outgoing pulse and its processing methods.

The paper discusses the laboratory prototype for the battery charging system with a resonance power converter that is investigated to develop a wireless charging system for movable devices using this technology as the basis. The text contains a theoretical description of such devices, as well as the experimental results including determination of the resonant frequency, research of the laboratory prototype in the cases when there is coils misalignment, and when the foreign object is located between the coils, and calculation of the overall system efficiency.The research established the wireless power transfer effectiveness depending on the distance between the coils and the misalignment distance. As a result, the threshold distance was found, at which the coupling coefficient of the coils decreases sharply, which leads to an abrupt decrease in the efficiency.In the final part of the paper, the necessity of further research aimed at the system’s mathematical model refinement is justified. Nevertheless, research of the laboratory prototype shows that within the identified limiting factors, the charging system based on wireless power transfer with the resonance power converter is efficient and can be scaled to wireless charge systems for movable devices.

Ultrasonic treatment of suspensions containing nanoparticles agglomerates can result in both fragmentation and consolidation of the agglomerates. It has been established with experiment that during prolonged ultrasonic impact (intensity of 4-8W/cm2) on oil suspensions of carbon of detonation synthesis there are variations in particle size (consolidation, fragmentation, again significant enlargement). The paper proposes possible mechanisms and provides a mathematical model to describe these processes.
