  • Abstract
    A novel mode-identification approach for permittivity measurement using traveling-wave (TW) whispering-gallery-mode (WGM) resonators is proposed. This approach is based on extracting the attenuation and coupling coefficients of the resonator directly from the measured complex insertion loss values. From both coefficients, the modal index of the resonance frequency will be easily identified. This approach is applied to an implemented K-band dielectric resonator where excellent results are obtained.
