图2. 压电板中SH型导波的前八阶频散曲线 (实线代表经典板,点划线代表取$f_{\rm c}=f_{\rm e} =0.5$ nm,$f_{\kappa }=f_{\rho } =1.0$ nm时的纳米压电板)

Fig.2. Dispersion curves of the first eight modes for SH guided waves in a piezoelectric plate (Solid lines indicate the case of the classical piezoelectric plate, and dashed-dotted lines indicate the case of the piezoelectric nanoplate with$f_{\rm c}=f_{\rm e} =0.5$ nm and$f_{\kappa }=f_{\rho } =1.0$ nm)
