摘要

声波传输操纵能力是声学超材料最重要的性能。为了控制声传输，采用组合声学超材料结构，构建了双向声穿透隐身方案。组合声超材料包括手性超材料和自准直超材料，在突防隐形中通过操纵声波传输路径绕过声散射目标，有效解决了目标散射隐身问题。最后，通过数值分析验证了有限宽声学超材料结构板的声传输操纵性能。研究结果为声学超材料控制声传输的设计和应用提供了技术支持。

Acoustic cloaking design based on penetration manipulation with combination acoustic metamaterials

The acoustic wave transmission manipulation ability is the most important performance for the acoustic metamaterials. To manipulate the acoustic transmission, the combination acoustic metamaterials structures are involved, and the two-directional acoustic penetration cloaking scheme are constructed. The combination acoustic metamaterials include chiral metamaterials and self-collimation metamaterials, the acoustic wave transmission path are manipulated to bypass from the acoustic scattering target in the penetration cloaking, and the target scattering stealth problem are effectively solved. In the end, the acoustic transmission manipulation performances are verified by numerical analysis with a finite-width acoustic metamaterial structure plates. The results provide technical support for design and application for acoustic transmission manipulation with acoustic metamaterials.
