Systematic design and experimental demonstration of transmission-type multiplexed acoustic meta-holograms
Yifan Zhu, Nikhil JRK Gerard, Xiaoxing Xia +6
Acoustic holograms have promising applications in sound-field reconstruction, particle manipulation, ultrasonic haptics and therapy. This paper reports on the theoretical, numerica…
Broadband inverted T-shaped seismic metamaterial
Yi Zeng, Shu-Yan Zhang, Hong-Tao Zhou +6
Seismic metamaterials (SMs) are expected to assist or replace traditional isolation systems owing to their strong attenuation of seismic waves. In this paper, a one-dimensional inv…
Extreme Low-Frequency Ultrathin Acoustic Absorbing Metasurface
Krupali Donda, Yifan Zhu, Shi-Wang Fan +3
We introduce a multi-coiled acoustic metasurface providing a quasi-perfect absorption (reaching 99.99% in experiments) at extremely low-frequency of 50 Hz, and simultaneously featu…
Broadband ultra-thin acoustic metasurface absorber
Yifan Zhu, Krupali Donda, Shiwang Fan +2
We theoretically and experimentally propose two designs of broadband low-frequency acoustic metasurface absorbers (Sample I/Sample II) for the frequency ranges of 458Hz~968Hz and 2…
Highly efficient acoustic refractive metasurfaces by harnessing near field coupling
Zhilin Hou, Xinsheng Fang, Yong Li +1
Typical acoustic refractive metasurfaces governed by generalized Snell law require several types of subwavelength subunits to provide an extra phase gradient along the surface. Thi…
Perfect anomalous splitter by acoustic meta-grating
Huiqin Ni, Xinsheng Fang, Zhilin Hou +2
As an inversely designed artificial device, metasurface usually means densely arranged meta-atoms with complex substructures. In acoustics, those meta-atoms are usually constructed…
