Cylindrical Resonator for Measurement the Parameters of Dielectrics Research

In microwave engineering, when considering dielectric losses of various structures, the main aspects are dielectric parameters and operating frequencies of the materials used. Evaluation of those parameters plays an important role in the development of advanced communication and electronic devices. Numerous approaches have been developed, which all have their advantages and disadvantages regarding various parameters of measurements. Among methods of determining dielectric parameters based on resonance, cylindrical cavity resonators are the most widespread. In this paper, some of the existing techniques will be revealed and the cylindrical cavity resonator method studied in depth. Main operational mode of the resonator that will be used in measurements is TM010. Simulations and experimental part of the project are, as well, present. Dielectric parameters of a Teflon sample will be found using both simulation and practical approach.
