ANALYSIS OF ELECTROMAGNETIC WAVES AND ANTENNAS FOR PRE-TREATMENT OF SEEDS IN A CONTINUOUS STREAM
Keywords:
electromagnetic technology, waves, antennas, generators, fluctuationsAbstract
Electromagnetic technology for pre-treatment of seeds needed source of microwave oscillations with high demands on fluctuation spectral and power characteristics. The article offers the opportunity to create the necessary sources based on avalanche-transit diodes. The research is based on analysis of the literature, according to which it can be concluded that the waveguide resonators are widely spread in the EHF, as in this range of quality factor higher than coaxial and stripline. Waveguide-pin and radial waveguide resonators are commonly used. Different types of antennas, the main ones: waveguide-slotted, surface wave antenna and horn are used in the EHF wavelengths. The result of the developed method follows that one of the main elements of the installation for pre-treatment of seed emitter EM energy that must form the desired radiation pattern and provide sufficient power flux density at the grain when moving conveyor beltReferences
