On the inaccuracy of using Mindlin's first-order plate theory for calculating the motional capacitance of a thickness-shear resonator.
We show that when using Mindlin's first-order theory of piezoelectric plates to analyze a thickness-shear mode resonator, while the frequency can be predicted accurately, the charge, the current, and hence the motional capacitance have significant inaccuracy.
