Abstract

This paper presents the results of an analysis using the finite plate technique of Y-cut langasite plan-parallel resonators with Al and Ag electrodes. We have extracted values for the piezoelectrically stiffened elastic stiffness c66D, the elastic stiffness c66E, the piezoelectric stress constant e11, and the dielectric permittivity ε11S. The measured material constants are in very good agreement with other reported values. This paper will present our new results on the langasite samples, and will include a comparison between an analysis of the data using the measurement method recommended by the current IEEE Standard on Piezoelectricity and the finite plate technique.
