Essay

The thesis is devoted to developing methods, models and devices, radio frequency electromagnetic radiation with optimal characteristics of non-thermal effect on biological objects (BO). Analysis of qualitative and quantitative characteristics of electromagnetic fields (EMF) from nonthermal effect on BO allowed to develop a model of gas-discharge source of excitation of broadband radiation of radiofrequency range. The parameters of the gas-discharge process have been estimated. A method for generating electromagnetic radiation (EMR) of radio-frequency range with non-thermal influence has been proposed. It is proved by taking into account discharge circuit characteristics and design and technological parameters of gas-discharge device that spark discharge may be used as a source of broadband electromagnetic radiation of low intensity by means of "flicker-noise" type signal. There is suggested a model of broadband radiator where coaxial electrode system of arrester (EMF exciter) is selected as a primary radiation source, and dielectric rod (antenna) acts as a guide function. Based on the results of modeling and experimental data, a method of calculation and selection of optimal design and technological parameters of the radiator using fractal analysis has been proposed. Theoretical and experimental data made it possible to develop a radiotechnical device generating low-intensity EMF of LF - EHF range with non-thermal effect on a CU, the parameters of which do not exceed permissible levels of energy flow in the microwave range for such countries as the USA, the European Union and Ukraine. A method of experimental research of biosensor devices under the action of radiation with the given electromagnetic characteristics was developed. The effectiveness of the developed radio-frequency device has been established, and the possibility of application of purposeful modification of biological parameters of the CU has been revealed. The means of formation of electromagnetic radiation of radio-frequency range with non-thermal influence has been developed. The radiotechnical device which operating principle is based on forming of electromagnetic radiation excited by periodic pulse gas discharge in the caoxial electrode system loaded on the dielectric rod antenna can be applied for obtaining of new knowledge about the action of low-intensity EMF on BO, which can be used.
