摘要:
本文提出了一种基于散射优化的声隐身材料参数的设计方法,可以在少量分层下实现良好的声波隐身效果,从而降低材料结构实现的难度。论文首先给出了平面声波入射各向异性圆柱隐身层的声场解析解,在此基础上对目标散射特性函数优化,得到声隐身材料的参数。

Abstract:
A method is proposed to design material parameters of acoustic cloaking materials based on the minimization of scattering cross-section. The proposed method can achieve good cloaking effect with a small amount of layered structures, thereby reducing the difficulty of practical implementation. Analyic solutions for plane acoustic wave incident on a multilayered and anisotropic cylindrical layers are derived. Material parameters are given by optimizing the scattering cross-section of the compound structures.
