Nondestructive Permittivity and Loss Tangent Measurements Using a Split-Cylinder Resonator



Michael D. Janezic, Edward Kuester, James R. Baker-Jarvis


In this paper we present a new theoretical model, based on the mode-matching method, for making nondestructive permittivity and loss tangent measurements using the split-cylinder resonator. This new model properly takes into account the fringing electric and magnetic fields, thereby improving the measurement accuracy of the technique. in order to verify the new split-cylinder model, we present permittivity and loss tangent measurement results for several dielectric substrates and show good agreement with measurements made in a conventional cylindrical cavity.
