Sažetak
We have developed a new and fast method for the determination of the complex frequency shift of a microwave resonant cavity. The method is based on frequency modulation of the microwave source around the cavity resonance and detection of the 2^nd and 4^th harmonic of the modulation frequency. With this procedure the static measurement of the response amplitude is not necessary and all the data are obtained through a single AC shannel. The optimal frequency deviation is shown to be comparable to the cavity resonance width.
