The source of dense low-temperature plasma (plasmatron) is widely used in physical experiments and engineering. In this device, a cold working gas is blown through the discharge region The torch produces cold plasma. The structures and characteristics of plasma are determined by electrodynamics properties of plasmatron. The goal of this work is the investigation of plasmatron electrodynamic characteristics. Hence the electrodynamic characteristics of a coaxial microwave plasmatron operating at a frequency of 10 GHz are studied.

The authors have found Laplace-Stiltiece transformation for the time of message delivery to the receiver, as well as its response in the form of appropriate controlling frames. We have obtained the expression for estimation of optimal mean value of scanning period. Boundary conditions of scanning period have been laid down for several routing methods.

An element of the reflective phased antenna array (RPAA) for the W-band with electrical beam-scanning is developed. The element contains a horn-dielectric radiator and waveguide ferrite phase shifter of a reflective type with magnetic memory, which produces a phase shift 0-400/spl deg/ in a 93-95 GHz frequency band. When a triangular grid element arrangement is used in an antenna array with 1.25/spl lambda/ spacing, the sector of the array scanning 2/spl theta/=30/spl deg/ is ensured.

The modification of the method of complex amplitudes for simulation of RF fields in microwave tube slow-wave circuits is proposed. It allows one to increase the broadbandness of the spectral models based on this method, up to values of the similar parameter obtained based on the method of instantaneous values models. All the advantages of complex amplitudes usage are retained. Modification is in the continuous monitoring of an electron beam oscillations spectrum with periodic adjustment of a set of model base frequencies. An example of the offered adaptive method applicability domain is given.

Experimental investigation results on phase stabilized fiber-optic link for transmission and distribution of microwave (UHF) and millimeter wave (EHF) reference signals are considered. The link under investigation operates in the remote optical self-heterodyne mode and contains two wavelength tunable laser sources, lengthy fiber transversal filter and Er-doped fiber amplifier. The designed link provides, in the frequency regions stated, transmitted reference signals with less than 1/spl deg/ phase instability with full compensation of the insertion loss.
