Acoustic metasurfaces derive their characteristics from the interaction between acoustic
waves and specifically designed materials. The field is driven by the desire to control …

Acoustic metamaterials have been widely investigated over the past few decades and have
realized acoustic parameters that are not achievable using conventional materials. After …

A severe limitation of current acoustic metasurfaces remains in their modest tunability to
meet multifrequency requirements and alterable functionalities on demand. Here, a …

Acoustic metamaterials (AMs) for sound wave manipulation have attracted significant
attention due to their fascinating functionalities, such as anomalous reflection/refraction …

We demonstrate multifunctional acoustic metasurfaces that can simultaneously realize the
same functionality or multiple different functionalities at multiple tunable frequencies. The …

Acoustic/elastic metasurfaces as a kind of two-dimensional metamaterials are of
subwavelength thickness and show remarkable ability of acoustic/elastic wave …

Metamaterials are artificially engineered materials that exhibit novel properties beyond
natural materials. By carefully designing the subwavelength unit cell structures, unique …

Although recent advances have made it possible to manipulate electromagnetic and
acoustic wavefronts with sub-wavelength metasurface slabs, the design of elastodynamic …

Abstract Space-coiling acoustic metasurfaces have been largely exploited and shown their
outstanding wave manipulation capacity. However, they are complex in realization and …

We propose an acoustic compound eye based on a three-dimensional meta-sphere, which
can achieve omnidirectional broadband acoustic signal enhancement. Imitating the insect …
