Abstract :
Properties of the TE02 higher order mode of a sapphire dielectric resonator are investigated. This mode has significantly higher unloaded quality factor Q than that of the TE01 mode. A significant reduction of the losses and corresponding increases in the unloaded Q of the resonator can be achieved by using superconductor enclosure covers. Detailed accurate quantitative analysis and results showing the improvements are presented. This resonator can be used in very-low-phase-noise oscillator applications
