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

Determination of parameters of closely spaced resonances using fractional-rational approximation of resonator frequency response

“…The magnitude of c is determined by the degree of overlap of the resonance peaks, and it determines the error in the determination of their parameters. The expression (11) coincides with normalized correlation coefficient. Fig.…”

“…Mathematical technique of continued fractions for realization a fractional-rational approximation of the frequency response of the resonator is considered in detail in [10,11]. The use of the fractional-rational approximation with step-by-step growing of the model order allows detecting high-Q resonances of coupled BCR in the case of practically complete overlapping [12].…”
