We investigate analytically the effect of the viscous dissipation of piezoelectric material on the dispersive and attenuated characteristics of Love wave propagation in a layered structure, which involves a thin piezoelectric layer bonded perfectly to an unbounded elastic substrate. The effects of the viscous coefficient on the phase velocity of Love waves and attenuation are presented and discussed in detail. The analytical method and the results can be useful for the design of the resonators and sensors.
我们通过分析研究了压电材料的粘性耗散对层状结构中Love波传播的色散和衰减特性的影响，该层状结构包括一个与无界弹性基底完美粘结的薄压电层。详细给出并讨论了粘性系数对Love波相速度和衰减的影响。该分析方法和结果可用于谐振器和传感器的设计。
