The plane-wave-expansion (PWE) approach dedicated to the simulation of periodic devices has been extended to 1-3 connectivity piezoelectric composite structures. The case of simple but actual piezoelectric composite structures is addressed, taking piezoelectricity, acoustic losses, and electrical excitation conditions rigorously into account. The material distribution is represented by using a bidimensional Fourier series and the electromechanical response is simulated using a Bloch-Floquet expansion together with the Fahmy-Adler formulation of the Christoffel problem. Application of the model to 1-3 connectivity piezoelectric composites is reported and compared to previously published analyses of this problem.
致力于周期性器件模拟的平面波展开（PWE）方法已扩展到1-3连通性压电复合结构。本文研究了简单但实际的压电复合结构的情况，严格考虑了压电性、声学损耗和电激励条件。通过二维傅里叶级数表示材料分布，并使用布洛赫-弗洛凯展开以及克里斯托费尔问题的法赫米-阿德勒公式来模拟机电响应。报告了该模型在1-3连通性压电复合材料中的应用，并与先前发表的关于此问题的分析进行了比较。
