Ultra-open High-efficiency Ventilated Metamaterial Absorbers with Customized Broadband Performance
Xiao Xiang, Xiaoxiao Wu, Xin Li +6
High-efficiency absorption of low-frequency sounds (< 1000 Hz) while maintaining a free flow of fluids remains a significant challenge in acoustical engineering due to the rigid tr…
Designing topological interface states in phononic crystals based on the full phase diagrams
Yan Meng, Xiaoxiao Wu, Ruo-Yang Zhang +8
The topological invariants of a periodic system can be used to define the topological phase of each band and determine the existence of topological interface states within a certai…
Type-II Dirac photons at the metasurfaces
Chuandeng Hu, Zhenyu Li, Rui Tong +9
Topological characteristics of energy bands, such as Dirac/Weyl nodes, have attracted substantial interest in condensed matter systems as well as in classical wave systems. Among t…
High-efficiency Ventilated Metamaterial Absorber at Low Frequency
Xiaoxiao Wu, Ka Yan Au-Yeung, Xin Li +7
We demonstrate a ventilated metamaterial absorber operating at low frequency (< 500 Hz).With only two layers of the absorption units, high-efficiency absorption (> 90%) has been ac…
