大的时间/存储成本已构成了一个重大的障碍，准确地分析表面声波（SAW）在大尺寸的二维（2-D）压电声子晶体（PnCs）。为了克服这一障碍，本研究引入了单位P-矩阵及其相关的级联。为了获得准确的单位P矩阵，使用三维有限元模型（FEM）分别推导出传输路径上有和没有二维压电PnC的声表面波延迟线的Y参数，并采用时间窗函数从P矩阵分析中提取所需信号。然后，单位P矩阵级联被用来获得SAW传播参数的大尺寸的压电PnC。用这种方法分析了铝（Al）/128°-YXLiNbO 3 PnCs中150个周期的声表面波。还进行了实验。为了选择合适的单位P-矩阵的大小，实验结果和理论结果之间的差异，以及时间/内存成本进行了比较，为不同的时期。结果表明，采用25个PnCs周期的单位P矩阵级联可以较好地获得150个周期以上的SAW传播参数。这表明了三维有限元法导出的单位P矩阵的准确性和P矩阵分析的有效性。
Large time/memory costs have constituted a significant obstacle for accurately analyzing surface acoustic waves (SAWs) in large-sized two-dimensional (2-D) piezoelectric phononic crystals (PnCs). To overcome this obstacle, this study introduces the unit P-matrix and its associated cascading. To obtain an accurate unit P-matrix, the Y parameters of the SAW delay lines were derived using a three-dimensional (3-D) finite-element model (FEM) with and without 2-D piezoelectric PnCs, respectively, on the transmitting path. A time window function was adopted to extract the desired signals from the P-matrix analysis. Then, unit P-matrix cascading was used to obtain SAW propagation parameters for the large-sized piezoelectric PnCs. Using this method, the SAW in aluminum (Al) /128°-YXLiNbO3 PnCs was analyzed over 150 periods. Experiments were also conducted. To choose the appropriate size of the unit P-matrix, the variance between experimental results and theoretical results, and time/memory cost were compared for different periods. The results indicate that cascading by unit P-matrix of 25 PnCs periods can be appropriately adopted to accurately derive the SAW propagation parameters over 150 periods. This indicates the accuracy of the unit P-matrix derived by 3-D FEM and the effectiveness of P-matrix analysis.
