Improving the performance of acoustic invisibility with multilayer structure based on scattering analysis

Cai Chen¹, Yuan Yin², Kan Wei-Wei³, Yang Jing¹, Zou Xin-Ye^{1, †,}

Normalized acoustic pressure fields for the plane wave source ((a) and (c)) and cylindrical wave source ((b) and (d)). The scattering sensor is protected by the 2-layer shell ((c) and (d)), and unprotected shell ((a) and (b)) separately.
