Directional radiation of sound waves by a subwavelength source
Xu-Dong Fan, Yi-Fan Zhu, Bin Liang +2
We propose and experimentally achieve a directional dipole field radiated by an omnidirectional monopole source enclosed in a subwavelength structure of acoustically hybrid resonan…
Ultra-thin Acoustic Metasurface-Based Schroeder Diffuser
Yifan Zhu, Xudong Fan, Bin Liang +2
Schroeder diffuser is a classical design, proposed over 40 years ago, for artificially creating optimal and predictable sound diffuse reflection. It has been widely adopted in arch…
Non-Hermitian acoustic metamaterial for the complete control of sound by accessing the exceptional points
Yi-Fan Zhu, Xue-Feng Zhu, Xu-Dong Fan +4
Non-Hermitian systems always play a negative role in wave manipulations due to inherent non-conservation of energy as well as loss of information. Recently, however, there has been…
An acoustic invisible gateway
Yi-Fan Zhu, Xin-Ye Zou, Bin Liang +3
The recently-emerged concept of "invisible gateway" with the extraordinary capability to block the waves but allow the passage of other entities has attracted great attentions due…
Broadband non-reciprocal transmission of sound with invariant frequency
Zhong-ming Gu, Jie Hu, Bin Liang +2
The emergence of "acoustic diode" (AD) capable of rectifying acoustic wave like electrical diodes do to electricity has been believed to be able to offer unconventional manipulatio…
Broadband omnidirectional invisibility for sound in three dimensions
Weiwei Kan, Bin Liang, Ruiqi Li +4
Acoustic cloaks that make object undetectable to sound waves have potential applications in a variety of scenarios and have received increasing interests recently. However, the exp…
Harry Potter's Cloak
X. F. Zhu, B. Liang, J. Tu +2
The magic "Harry Potter's cloak" has been the dream of human beings for really long time. Recently, transformation optics inspired from the advent of metamaterials offers great ver…
