Abstract

A new approximate method for calculating the electromechanical coupling factors (k_p and k₃₁) related to transverse vibration in piezoelectric ceramics is proposed, which is applicable to a wide range of coupling factors with a considerable mechanical loss. The induced-piezoelectric resonance was measured by the transmission method on PMN-based electrostrictive resonators under an applied bias field. The electromechanical parameters were determined by using the new approximation in the temperature range -100°C to 100°C under fields up to 12×10⁵ V/m. The electrostrictive Q₃₁ coefficient obtained is -5.5×10⁻³ m⁴C⁻² for PMN, which is in good agreement with that determined by other methods.
