| Abstract: | Approximate formulas are obtained for various parameters of a piezoelectric material in the form of a disk, which do not require the calculation of the least (first) root of the frequency equation. To calculate approximately the planar electromechanical coupling coefficient, one can simplify the measurement procedure because it is not necessary to measure the first overtone frequency and determine Poisson's ratio. |
