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.
