Based on the one-dimensional finite element method reported in References 1 and 2, a general formulation is presented for the calculation of the conductorQ-factor,Qc, associated with metallic losses of cylindrical cavity resonators loaded axisymmetrically with dielectrics. The formulation is employed to accurately determineQcrelating to the first few modes of the cylindrical cavity resonator loaded with a hollow cylindrical dielectric as well as to obtainQcrelating to the fundamental mode (TE01δ) of the ring resonator on a microstrip substrate.
