| Abstract: | The whispering gallery modes (WGM) in the sapphire are analyzed by axial+radial mode matching method,including the WGM resonant frequency and the electromagnetic field distribution. Also the influence of the cavity in the resonator design is analyzed here. Finally a whispering gallery high Q sapphire resonator was fabricated and tested. The measured load-Q is 45 000,and the insertion-loss is lower than9 dB at the resonant frequency 10.99 GHz. The resonator's performance is good and this resonator is very su... |
