The present article deals with the reflection and transmission of waves at an interface of piezoelectric (ALN & PZT-5T) half-spaces with microstructures. Unlike the classical piezoelectric material, in the considered media, five coupled waves (2 bulk and 3 surface) [namely the Quasi-longitudinal wave (QP), Quasi-transverse wave (QSV), Electric-acoustic wave (EA), P-type surface wave (SP) and S-type surface wave (SS)] are generated in response to an oblique incident Quasi plane wave. The main objective of this study is to investigate the influence of the characteristic length of microstructure, the inertial characteristic length and flexoelectric coefficients on the reflection and transmission coefficients. For this purpose, the linear algebraic equation, continuity conditions at the common interface are contracted. The linear system of equations comprising the reflection and transmission coefficients is derived, which is solved by using the Cramer's rule. The consequence of this electromechanical phenomenon may be advantageous in certain engineering applications that involve smart nano-composites.

本文讨论了具有微结构的压电（ALN 和 PZT-5T）半空间界面处波的反射和传输。与经典压电材料不同，在所考虑的介质中，有五个耦合波（2 个体和 3 个表面）[即准纵波 (QP)、准横波 (QSV)、电声波 (EA)、P-型表面波 (SP) 和 S 型表面波 (SS)] 是响应倾斜入射准平面波而产生的。本研究的主要目的是研究微结构特征长度、惯性特征长度和挠电系数对反射和透射系数的影响。为此，线性代数方程，公共界面处的连续性条件被压缩。导出包含反射系数和透射系数的线性方程组，并使用克莱默规则求解。这种机电现象的结果在涉及智能纳米复合材料的某些工程应用中可能是有利的。
