Abstract
A method for measuring the complex dielectric constant of materials using a resonant method based on a biconic resonator is presented. An improved design of the measuring chamber is proposed, which ensures high quality and stability of resonant frequencies. An algorithm for processing the results has been developed, including identification of resonant modes, calculation of the parameters ε′ and ε′′, as well as correction of errors related to sample geometry and field inhomogeneity. Numerical simulation was performed in CST Microwave Studio. The data obtained confirm the accuracy and reproducibility of the proposed resonant method in the microwave frequency range.
