A General Framework of Bound States in the Continuum in an Open Acoustic Resonator
Lujun Huang, Bin Jia, Artem S Pilipchuk +11
Bound states in the continuum (BICs) provide a viable way of achieving high-Q resonances in both photonics and acoustics. In this work, we proposed a general method of constructing…
Achromatic metasurfaces with inversely customized dispersion for ultra-broadband acoustic beam engineering
Hao-Wen Dong, Chen Shen, Sheng-Dong Zhao +7
Metasurfaces, the ultrathin media with extraordinary wavefront modulation ability, have shown versatile potential in manipulating waves. However, existing acoustic metasurfaces are…
Transfer matrix method for the analysis of space-time modulated media and systems
Junfei Li, Xiaohui Zhu, Chen Shen +2
Space-time modulation adds another powerful degree of freedom to the manipulation of classical wave systems. It opens the door for complex control of wave behavior beyond the reach…
Non-reciprocal sound propagation in space-time modulated media
Junfei Li, Chen Shen, Yangbo Xie +1
Realization of non-reciprocal devices, such as isolators and circulators, is of fundamental importance in microwave and photonic communication systems. This can be achieved by brea…
Perfect Generation of Angular Momentum with Cylindrical Bianisotropic Metasurfaces
Junfei Li, Ana Díaz-Rubio, Chen Shen +3
Recent advances in metasurfaces have shown the importance of controlling the bianisotropic response of the constituent meta-atoms for maximum efficiency wavefront transformation. U…
A Surface Impedance-Based Three-Channel Acoustic Metasurface Retroreflector
Chen Shen, Ana Díaz-Rubio, Junfei Li +1
We propose the design and measurement of an acoustic metasurface retroreflector that works at three discrete incident angles. An impedance model is developed such that for acoustic…
