The solution to the scattering of an incident pressure wave by an arrangement of eccentric cylinders embedded inside a pair of concentric cylinders is derived here using a combination of T-matrix and mode-matching approaches. This method allows the generation of synthetic data from relatively complex structures to be used for the validation of acoustic tomography methods. An application of the solution derived here is illustrated by reconstructing sound speed and density profiles from a complex phantom using inverse scattering.
本文采用 T 矩阵和模式匹配方法的组合，推导了入射压力波通过一对同心圆柱内嵌入的偏心圆柱排列的散射问题的解决方案。该方法允许从相对复杂的结构生成合成数据，用于声学层析成像方法的验证。本文推导的解的一个应用是通过逆散射从复杂的体模重建声速和密度分布。
