| Popis: | An alternative method to determine the electromechanical coupling constant k13 for the length-thickness piezoelectric resonator is presented. Data relating the electromechanical coupling constant k13 to the parallel resonance frequency ratios are tabulated. A third order polynomial was found to represent the relationship accurately for k13 = 0.01 to 0.6. The coefficients of the polynomial and typical errors in the fit are reported. |
