Investigation of SH wave propagation in piezoelectric plates

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.
