Abstract
The standard IEEE procedure for determining the piezoelectric dielectric, and elastic constants associated with the radial mode resonance of piezoelectric materials neglects the imaginary components of these constants. This report presents a method to determine the complex form of the above constants. These constants are calculated from the experimental values of the first and second series resonance frequencies, the first parallel resonance frequency and appropriate half band frequencies and the low frequency admittance of the material, all of which can be measured on one disk sample. The method has also been used to automate the current IEEE procedure for determining the real parts of the material constants.
