The analysis of the natural frequency and estimation of Q-factor of the open resonator by means of fractional-rational approximation of the reflection response has been considered. An advantage of the proposed technique in comparison with the classical methods has been demonstrated. Dependence of Q-factor of the shielded half-disk dielectric resonator and estimations of the poles and the zeros of the resonance response against the coupling coefficient value has been analyzed.References
