  • Abstract
    We present a new ID resonator modeling through a polynomial approach. We have determined, for different values of the metallization thickness, the series and parallel resonance frequencies, the field profiles within the structure, and the effective electromechanical coupling coefficient and the Q-factor as well. To assess and validate the approach, the results are compared against other calculations from the literature.
