On the basis of a method of statistical modeling investigations of basic mechanisms of dispersion in semiconductor heterostructures and basic characteristics of a physical process of carrier transfer in a mode with occurrence of plasma waves are carried out. Novelty consists in statistical modeling and self-co-ordinated solution of Schroedinger equation. It all allows revealing of basic physical mechanisms, determining the increase of propagation velocity of plasma waves, and defining of requirements of a choice of electrophysical parameters of heterostructures for production of oscillations in the millimetric range.

The comparison of calculation of radio attenuation in the recommendations ITU-R P.452, and ITU-R R.1546 has been carried out. In the process of analysis the differences has been revealed: the first, calculates attenuation throughout the flight path in detail, and the second, uses approximized empirical curves. It follows that the recommended guideline ITU-R P.452 is for precise calculations, and ITU-R R.1546 is for “fast”.

An analytical estimation has been performed to determine the optimal parameters of pulsed magnetrons, operating at a spatial harmonic at a frequency of 35 GHz and an anode voltage of 6.5 kV in the drift-resonance mode, with the main cathode being the cold secondary-emission one. A 3D simulation experiment on a magnetron with the analytically determined characteristics has been conducted to check its adequacy in providing the required energy parameters. The breadboard magnetrons have the number of vane-type resonators in the anode unit N = 20 and N = 16, respectively. The both magnetrons have generated the electromagnetic radiation in the Ka range with the magnetic field being slightly above 0.4 T. It was proven that it is possible to create a full-functional Ka-range magnetron with a relatively low anode voltage and such parameters that enable its wide applicability.
