| Abstract: | The thickness-shear vibration of piezoelectric substrate is numerical analyzed by the finite-difference time domain(FDTD) method.The piezoelectric governing equations and acoustic equations are reconstructed to satisfy the DDTD method's require,the equations are discretized in spatial and temporal domain by the FDTD method,and the numerical results in the time domain can be obtain directly.The electric characteristic admittance is presented by this method,and the result of the example is demonstrated to be ... |
