Abstract
Based on Mindlin´s early work, we calculate and plot optimal electrode shape and size of Y-cut quartz, At-cut quartz, and Y-cut langasite plate thickness-shear resonators. The electrodes obtained are optimal in that they satisfy Bechmann´s number in every direction. The results are useful in the design optimization of these resonators.
