Abstract
Introduction. The low-intensity noise generators of millimeter wavelength range find wide application in the engineering, biological appliance and therapy procedures due to the simplicity, reliability and efficiency at treatment of pain syndromes in the different branches of practical medicine. Design of the low-intensity noise generator. The features of low-intensity noise generator are electromagnetic waves generation by means of the radiation source (working substance) that has a temperature more or less of the environment ambient temperature. Structurally the radiation source is made as a millimeter range waveguide matched load. It is enclosed and heat-insulated. One of basic lacks of similar noise generators is small initial power. Authors have proposed two variant of the noise generator power increasing. Their experimental stud-ies results and choice of natural origin (minerals) materials prompt are undertaken for the working substance of thermal generator and more effective construction of cool element of-fers. Enhancement of the noise generator power. Utilization of mineral (for example, nephrite) as working substance provides the double increase of noise initial signal power in comparison with standard material – ferroepoxide usually used in microwave technique. The multi-layered construction of Peltier element provides the value of working substance temperature in range 20-30оС accordingly increases power of negative electromagnetic stream. Conclusion. Thus the proposed low-intensity noise generator design provides greater efficiency at its use in the engineering, biological appliance and therapy procedures of practical medicine.
