Plate resonators (dimensions: $13^{L}\times 4.0^{W}\times 0.36^{T}$ mm3) composed of relaxor single-crystal plates with a giant $k_{31}$ (${>}80$%) in Pb[(Zn1/3Nb2/3)0.91Ti0.09]O3 (PZNT91/09) with the (100) plane and Pb[(Mg1/3Nb2/3)0.74T0.26]O3 (PMNT74/26) with the (110) plane were investigated regarding their vibration modes in the directions of length ($k_{31}$ mode) and width ($k_{32}$ mode). Frequency response analysis of impedance on the giant $k_{31}$ mode was evaluated by a finite element method (FEM) and the simulated data by FEM were compared with the measured results. A large anisotropy of the Poisson ratio of the length direction ($\sigma_{L}^{\text{E}}$) and the width direction ($\sigma_{W}^{\text{E}}$) was observed and the ratios of $\sigma_{W}^{\text{E}}/\sigma_{L}^{\text{E}}$ reached 3.2–3.4 in the PZNT91/09 single-crystal plates and 4.5–4.9 in the PMNT74/26 single-crystal plates. Although $\sigma_{W}^{\text{E}}/\sigma_{L}^{\text{E}}$ was fixed at 3.2 (PZNT91/09) and 4.9 (PMNT74/26), $\sigma_{L}^{\text{E}}$ and $\sigma_{W}^{\text{E}}$ were further changed; the simulated data were well fitted to the measured data in the cases of the PZNT91/09 and PMNT74/26 single-crystal plates. In the PZNT91/09 single-crystal plates, the Poisson ratio on the $k_{31}$ and $k_{32}$ modes affected the frequency response of impedance in the $k_{\text{t}}$ mode, which corresponds to thickness vibration of the plate. However, the Poisson ratio in the PMNT74/26 single-crystal plates was independent of the frequency response of impedance in the $k_{\text{t}}$ mode. Moreover, the domain behavior of the PZNT91/09 single-crystal plates could be explained by the simulated impedance responses on the third overtone of the $k_{31}$ fundamental vibration.
