Scalable Metagrating for Efficient Ultrasonic Focusing
Yan Kei Chiang, Li Quan, Yugui Peng +4
Acoustic focusing plays a pivotal role in a wide variety of applications ranging from medical science to nondestructive testing. Previous works have shown that acoustic metagrating…

Reciprocity of thermal diffusion in time-modulated systems
Jiaxin Li, Ying Li, Pei-Chao Cao +6
The reciprocity principle governs the symmetry in transmission of electromagnetic and acoustic waves, as well as the diffusion of heat between two points in space, with important c…

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…
