─介绍了压电材料弹性动力波的完全匹配层（PML）。导出了PML方程的匹配条件，以减少边界的杂散反射。利用时域有限差分法（FDTD）模拟了波在压电材料中的传播。结果表明，所提出的PML边界具有良好的性能。索引项─弹性波、时域有限差分、压电材料、PML、SAW。
─ A perfectly matched layer (PML) is introduced for elastodynamic waves in piezoelectric materials. A matching condition is derived for the PML equations to reduce spurious reflections from the boundary. The finite difference time domain (FDTD) is used to model the propagation of the wave in the piezoelectric material. The results show good performance of the proposed PML boundary. Index Terms ─ Elastodynamic wave, FDTD, piezoelectric materials, PML, SAW.
