It was found that due to the their different acoustic penetration depths inside the liquid the changes of the surface characteristics of the sensor and the characteristics of liquid near the surface can be identified respectively by combined A0 and S0 modes simultaneously. At the same time  the mass sensitivities of both A0 mode and S0 mode of a 2m Lamb wave sensor were demonstrated experimentally. It was proved that S0 mode has higher sensitivity to surface mass changes and the mass sensitivity of the acoustic sensor can be improved further.   Energy transportation characteristics of surface acoustic wave guided by PbZr0.52Ti0.48/Si configuration (EI CONFERENCE) 会议论文 Liu J.; Lee C.; No K. 收藏  |  浏览/下载：9/0  |  提交时间：2013/03/25 A PbZr0.52Ti0.48/Si structure has been made and analyzed using Farnell theory. The surface acoustic wave (SAW) decay factors and corresponding eigenvectors have been calculated in the layer and substrate  respectively. It was indicated that there is energy exchange between particle displacement u1 and u3 in the propagation of surface acoustic waves. 2001 Taylor Francis.
