The paper presents materials of the investigation into the single-phase process of desulfuring of the diesel fuel with the use of the microwave electromagnetic energy process as an initiator at a temperature not exceeding 100 °C. Aluminum, zinc, copper and iron ions were used as chemisorbents, which enable to obtain the residual sulfur content at the level of the EURO-4 standard, and with the use...
Materials of experimental studies on intensification of water desorption out of molecular sieves under the action of microwave electromagnetic energy are given. A possibility of realizing a continuous process of dewatering out of alcohol through a molecular sieve and intensification of this process under the impact of a controllable microwave electromagnetic energy level are shown.
For six-port vector analyzer based on the E-plane waveguide cross-connection of rectangular waveguides, the benefits of determining the values of the complex reflection coefficient with the application of the principles of holography with three reference signals were approved. The value of the condition number of the matrix system of linear algebraic equations formed according to the methods processing...
Systematic joint studies being done in laboratory and field conditions, enabled to develop a scientific concept of microwave energy influence on the rate of growth of grain crops under a considerable reduction of chemical reactants. A model is developed that explains the effect of intensity and duration of microwave energy impact on the change of germination energy, germinating ability and productivity...
This paper considers principles of construction and methods of analysis of electro-optical probing and characterization of the Brillouin gain contour, based on using the methods of poly-harmonic probing radiation and estimation of the parameters by evaluation of envelopes of its beating frequencies at stages of searching the center frequency, the maximum gain and the width of the contour determination,...
The implementation of non-absorbent polymers thermal destruction initiated by indirect heating in an intense electromagnetic microwave field using carbon thermal conversion elements is considered. Results of theoretical analysis based on mathematical modeling and experimental investigation into depolymerization of the polymer are analyzed. Polystyrene and polymethylmethacrylate are the investigated...
The experimental investigations of the impact of low-intensity electromagnetic fields of extremely high frequency on morphometric growth parameters of potato tubers seedlings, as well as growth parameters of plants and potato tubers are carried out in the “Scientific Research Institute of Applied Electrodynamics, Photonics and Living Systems ” (SRI AEPLS). This article presents the results of investigations,...
In this paper the modulation methods for poly-harmonic microwave signals on optical carrier forming and detecting are demonstrated, especially for applications in fiber-optic sensor systems. The methods of the single-frequency optical signal conversion into the poly-harmonic ones with the difference frequency between the components of SHF, UHF and partly EHF bands has been proposed. In order to form...
