Efficient, High-purity, Robust Sound Frequency Conversion with a Linear Metasurface
Chengbo Hu, Wei Wang, Jincheng Ni +5
The intrinsic limitation of the material nonlinearity inevitably results in the poor mode purity, conversion efficiency and real-time reconfigurability of the generated harmonic wa…
Experimental Observation of Efficient Nonreciprocal Mode Transitions via Spatiotemporally-Modulated Acoustic Metamaterials
Zhaoxian Chen, Yugui Peng, Haoxiang Li +7
In lossless acoustic systems, mode transitions are always time-reversible, consistent with Lorentz reciprocity, giving rise to symmetric sound manipulation in space-time. To overco…
Meta-neural-network for Realtime and Passive Deep-learning-based Object Recognition
Jingkai Weng, Yujiang Ding, Chengbo Hu +4
Deep-learning recently show great success across disciplines yet conventionally require time-consuming computer processing or bulky-sized diffractive elements. Here we theoreticall…
Experimental Realization of Acoustic Chern Insulator
Yifan Zhu, Yugui Peng, Xudong Fan +4
Topological insulators are new states of matter in which the topological phase originates from symmetry breaking. Recently, time-reversal invariant topological insulators were demo…
