Abstract :
Recently, complete matrix sets of coefficients have appeared in the literature for three different single crystal relaxor ferroelectric materials. This paper analyzes these sets for self consistency and compares modeled resonator impedance curves to those measured for actual samples. Based on these results, conclusions are drawn regarding the accuracy of each matrix. Possible causes of coefficient errors are discussed
