Abstract

We report a procedure for determining both the permittivity and the permeability of a small dielectric–magnetic sample by means of a cylindrical resonator supporting the circularly symmetrical TM010-mode. The method is based on perturbation theory and involves measurements of the shift of the resonance frequency and the quality factor Q for several different sample positions.
