In this paper, the propagation of transversally horizontal waves (SH) propagating in a piezoelectric plate is investigated. The dispersion curve is obtained numerically in the frequency domain by employing the power series technique (PST). In order to verify the sensitivity of the SH wave characteristics to different piezoelectric plate properties, the effect of each plate property is studied separately. Through different plates, the influence of each plate property on dispersion and SH wave structure is discussed. The electrically open and shorted conditions are considered. The study is focused on the first three SH modes. It is shown that the plate properties can be classified into two categories. Further, there is compensation between their effects on the phase velocity, electromechanical coupling coefficient, and SH wave structure. These results can be useful for the designs of acoustic wave devices.

压电板中SH波传播的研究

在本文中,研究了在压电板中传播的横向水平波 (SH) 的传播。频域曲线是通过使用幂级数技术 (PST) 在频域中以数值方式获得的。为了验证SH波特性对不同压电板特性的敏感性,分别研究了每种板特性的影响。通过不同的板块,讨论了各板块特性对色散和SH波结构的影响。考虑电气开路和短路情况。该研究集中于前三种 SH 模式。结果表明,板材特性可以分为两类。此外,它们对相速度、机电耦合系数和 SH 波结构的影响之间存在补偿。
