Objective. The article discusses energy-saving thermoelectric generators for autonomous power supply of the cooling apparatus of heat-generating electronic components.Method. Methods of modeling heat exchange processes in the operation of thermoelectric generators based on the Seebeck effect are applied. The heated and cooled zones of the generator are topologically spaced to reduce parasitic conductive transport. The semiconductor branches are manufactured using thin-film technology to reduce parasitic Joule heat emissions. The materials of the junctions and electrodes are selected taking into account the energy of the electrons.Result. Energy saving of processes has increased in thermoelectric generators by reducing parasitic Joule heat generation, reducing parasitic conductive transfer and additional energy generation from metal electrodes.Conclusion. The conducted studies allow us to conclude that in order to increase the energy saving of thermoelectric generators for autonomous power supply of the cooling apparatus of the heat-generating electronic components, it is necessary to topologically separate the heated and cooled zones of the generator into different levels in space, and to manufacture semiconductor branches using thin-film technology and additionally cool the generator junctions with ventilation, and additionally recover energy from the heat-generating components on the heated junctions.

Objective. The aim of the study is to simulate resonators for microwave digital active phased antenna arrays (DFAAR) in the microwave range, which will optimize the parameters of the antenna system for more reliable direction finding with high reliability of any aircraft. Method. The use of one-sided surfaces in the Mobius shape as resonators makes it possible to implement a new type of microwave resonators in the form of an integrated capacitance and a two-turn inductance. The parameters of such a resonator make it possible to realize a traveling or standing wave, depending on the geometric dimensions. Result. The use of innovative resonators for microwave DFAAR with p-i-n diodes to change the area of the capacitor makes it possible to implement a two-frequency method of pulse-code modulation. On the basis of such resonators, it is possible to realize a standing wave at one position of the p-i-n diodes, and a traveling wave at the other. Such electromagnetic waves, transmitted by the DFAAR, can track objects in the stealth mode. Conclusion. The use of traditional resonators for DFAAR of the microwave range allows you to discretely adjust the parameters of these resonators by turning on / off p-i-n diodes with positive and negative voltages to control the frequency properties of the resonators and set the traveling or standing wave modes.
