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

Passive acoustic wave manipulations are severely constrained by the narrow frequency
bandwidth of acoustic metastructures. In this research, an unprecedented type of …

We investigate the transverse trapping force acting on a small particle on or off the central
axis of zero-order finite Bessel beams. Combining the simulated fields with the Gorkov force …

Broadband sound absorption has consistently been a challenge in designing underwater
sound absorption structure (USAS). Most research of USASs achieve broadband sound …

We report on the theoretical, numerical, and experimental investigation of secure acoustic
holography. This secure holography is achieved via an encoded hologram generated by a …

Acoustic cloaking has received significant interest due to the appealing ability to render an
object acoustically invisible. In a similar concept to acoustic cloaking, acoustic illusions …

声学/弹性超表面是一类亚波长厚度的二维超材料, 具有很强的声波/弹性波操控能力,
在声学成像, 通信, 隐身, 伪装, 振动/噪声控制, 能量收集, 无损检测等领域具有潜在的应用 …

Acoustic and elastic waves can be manipulated by a novel artificial metasurface, usually
composed of different microstructures. In this paper, the topology optimization technique was …

Abstract Two-dimensional (2D) acoustic vortex allows new physics and applications different
from three-dimensional counterparts, yet existing mechanisms usually have to rely on active …

Narrow bandwidth and specific incident angle are the main drawbacks in real-life
applications for the existed carpet cloaking based on the acoustic metasurface (AM). Here …
