Building transmitter circuit for the study of parameters of system of secondary emitters
Suggest a method for constructing a system of magnetic coils, of the workspace in which excited облучающее sample magnetic field used to study the parameters of the system of secondary emitters. Theoretically formulated and practically implemented model of the feed, providing the creation of a uniform magnetic field on the stage. The measurements of the distribution of magnetic field in облучателе to judge the appropriateness ...
Building an optical local noise-resistant communication network
The authors considered the possibility of using Li-Fi technology using one main emitting LED and several re-emitting LEDs to provide subscriber access. The use of this method allows achieving a throughput of up to 10 Gbit / s.

On the possibility of improving the physical parameters of the receiving and transmitting antenna system
... size characteristics, which is most important in order to ensure communication with remote mobile objects. Giving a certain configuration to the antenna vibrators while using several coplanar lines and ensuring the joint operation of several antenna emitters allows you to significantly reduce the overall size of the structure while ensuring high power output. The construction of a radio frequency module according to a multi-channel scheme makes it possible to increase the range of operating frequencies ...

Modeling of the cathode thermal conditions
... on the calculations, the cathode thermal model and operating performances were assessed, the most efficient required cathode life time characteristics were selected, which are related to the cathode heater power and operating time with provision of emitter optimal temperature in the automatic mode and welded joints leak-tightness. It was determined that the minimum heater power for cathode start-up is 60 W, the time to prepare for a start-up is 140 sec. To improve the cathode stable operation it ...
