The slot-line as element of excitation of quasioptic hemispherical resonators for the solving problems of dielectrometry liquids

A measuring cell of dielectrometer on the basis of flat metal hemispherical resonator with whispering galley modes for the research of electrophysical characteristics of different liquids is proposed. It is proposed to use a slot line in order to minimize the external factors of resonance field´s disturbance for activation the whispering gallery vibrations in the measuring cell. There were investigated different samples of liquids like benzene, butanol, ethanol and methanol. A high resolving capacity of measurement is shown, that at the same time, allow to identify its changes of electrodynamic characteristics of the introduced measuring cell of resonance type. There have been developed recommendations concerning the volumes of the tested samples. It was shown, that cited research method of electrophysical parameters of different liquids in the represented measuring cell has restriction of disturbance value of the resonance fields with the help of liquids.
