Radiophysical Characteristics of a Radiator Based on a Gas Discharge Plasma.

摘要

The results of the study of characteristics of a microwave radiator based on cold plasma of a gas discharge are presented. A method of determining the plasma conductivity in the given frequency band is proposed and discussed. As plasma always contains free charges electrons and ions see 1 its excitation by a source of alternating voltage results in appearance of alternating current. For a certain electrical size of plasma segments this leads to the radiation of time-varying electromagnetic field 2. Experimental research of a loop radiator based on cold plasma of a gas discharge 3 has shown that the bandwidth properties of its radiation characteristics and input impedance considerably exceed those of antenna based on conductors of similar configuration.
