Analysis of Q-factor of dielectric resonator by means of fractional-rational approximation of reflection response

Abstract

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 classical methods has been demonstrated. Dependence of Q-factor of the half-disk dielectric resonator and estimations of poles and zeros of resonance response against coupling coefficient value has been analyzed.
