To control the complex energy flow between neighboring microstructures for realizing extreme acoustic functionality using a large-scale non-local metamaterial, here this paper shows that collaborative topology-optimization methodology is developed to construct gradient metasurfaces with smooth boundaries broadband large-angle reflection. An inverse-designed metasurface numerically and experimentally validated support large reflection angles within low-frequency range while maintaining high efficiency greater than 98.9%. It further revealed strong exchange multiple adjacent optimized can enable arbitrary surface impedances, thus obtaining efficient anomalous from 52° 90°. The present not only applicable airborne waves, but also be extended customization of wave functionalities elastic underwater metasurfaces.
