Phononic Skyrmions
Liyun Cao, Sheng Wan, Yi Zeng +2
Skyrmions with topologically stable configurations have shown a promising route toward magnetic and photonic materials for information processing due to their defect-immune and low…
Elastic Bound State in the Continuum with Perfect Mode Conversion
Liyun Cao, Yifan Zhu, Yanlong Xu +3
The partial or complete confinement of waves in an open system is omnipresent in nature and in wave-based materials and technology. Here, we theoretically analyze and experimentall…
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…
