Reflection and Transmission Spectrum of Sound at Anisotropic Solid Layer

考虑到由流体斜入射到各向异性固体时超声波模式转换的一般情况 ,研究了浸没于流体中一般各向异性固体层状材料的声反射和透射问题 ,给出了问题的求解方法 ,得到各向异性固体层的声反射和透射系数是介质参数 ,固体层取向和厚度 ,入射角及入射波频率的函数 。

Calculation methods are presented for the reflection and transmission spectrum of the ultrasonic waves incident from the fluid onto the general anisotropic solid layer. It is found that the sound reflection and transmission coefficients depend on the media parameters, orientation and thickness of the solid layer, incident angle and sound wave frequency. The examples of numerical solution of the sound reflection and transmission spectrum are obtained for a fluid loaded orthorhombic symmetry composite materials plate.
