The SAW sensors include Rayleigh wave, shear horizontal acoustic plate wave, Love wave and Lamb wave sensors. 表面声波传感器依其波型分类,主要包括瑞利波、水平切变声板波、乐甫波和兰姆波传感器;
The shear horizontal winds decreases the vertical wave length of wave packet. 重力波在剪切风场中非线性传播时垂直波长随高度的增加而减小。
The scattering of shear horizontal ( SH ) waves in a layered composites with weakly bonded interfaces was discussed by using the shear spring model of infirm interface and the theories of elastic waves, and also the analytical solution was obtained. 对含有弱界面的复合材料层合板,采用弱连接界面的剪切弹簧模型,借助波函数法研究了水平剪切(SH)波入射时层合板对波的散射,得到了解析结果。
