Abstract :
Based on the one-dimensional finite element method a general formulation is presented for the calculation of the conductor Q-factor, Qc, associated with metallic losses of cylindrical cavity resonators loaded axisymmetrically with dielectrics. The formulation is employed to accurately determine Qc relating to the first few modes of the cylindrical cavity resonator loaded with a hollow cylindrical dielectric as well as to obtain Qc relating to the fundamental mode (TE01 delta ) of the ring resonator on a microstrip substrate.
