In article number 2002251, Lei Ye, Hai‐Rong Zheng, Jian‐Bin Xu, Gary J. Cheng, Xue‐Feng Zhu, and co‐workers implement a microstructured meta‐skin insulator to reflect acoustic waves in an all‐angle and wide spectrum range, due to the tremendous impedance mismatch at the superhydrophobic air/water interface. This strategy in particular, has application potential for underwater acoustic metamaterials, since the detrimental solid–fluid coupling can be substantially diminished by coating the metaskin insulator on the designed metastructure.

超表面：声学超皮肤绝缘体（Adv。Mater。37/2020）

在编号2002251中，叶磊，郑海荣，徐建斌，成加利，朱学峰和同事们实现了一种微结构化的亚表皮绝缘体，可全方位反射声波频谱范围，这是由于超疏水性空气/水界面处的巨大阻抗失配。这种策略尤其具有在水下声学超材料中的应用潜力，因为通过在设计的元结构上涂覆超薄皮绝缘子，可大大减少有害的固液耦合。
