FIELD: physics.
SUBSTANCE: method of measuring electromechanical coupling constants of piezoelectric material K involves measuring the frequency dependency of scalar impedance and measuring the difference between resonance and antiresonance frequencies. The frequency dependence of the imaginary part of impedance of the resonator is also measured and the difference in extrema frequencies is found.
EFFECT: high accuracy of measuring electrochemical coupling constants of layers and films of piezoelectric material and broader range of measurement frequencies.
