Abstract
The energy trapping characteristics for thickness extensional (TE) mode vibration were studied for preferentially orientated zinc oxide (ZnO) ceramics fabricated by the chemical transfer method. The results of both the dispersion curve analysis and the finite-element method (FEM) simulation indicate that frequency-lowering-type energy trapping is possible for ZnO ceramics. The number of generating mode in the ZnO ceramic plate decreases with decreasing diameter of the electrode in the experiment. This means that the energy trapping characteristics were obtained on the ZnO ceramics. However single-mode energy trapping was not realized in this study.
