Manually Tunable Ventilated Metamaterial Absorbers
Xiang Xiao, Hongxing Tian, Yingzhou Huang +2
For most acoustic metamaterials, once they have been fabricated, their operating frequencies and functions cannot be adjusted, which is an intrinsic barrier for development of real…
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…
Deterministic scheme for two-dimensional type-II Dirac points and experimental realization in acoustics
Xiaoxiao Wu, Xin Li, Ruo-Yang Zhang +7
Low-energy electrons near Dirac/Weyl nodal points mimic massless relativistic fermions. However, as they are not constrained by Lorentz invariance, they can exhibit tipped-over typ…
Interlayer Topological Transport and Devices based on Layer Pseudospins in Photonic Valley-Hall Phases
Xiaoxiao Wu, Zhenyu Li, Jian Chen +8
Valley-Hall phases, first proposed in two-dimensional (2D) materials, originate from nontrivial topologies around valleys which denote local extrema in momentum space. Since they a…
Su-Schrieffer-Heeger Model Inspired Acoustic Interface States and Edge States
Xin Li, Yan Meng, Xiaoxiao Wu +4
If a full band gap closes and then reopens when we continuously deform a periodic system while keeping its symmetry, a topological phase transition usually occurs. A common model d…
Breakdown of diffusivity-entropy scaling in colloidal glass forming liquids
Bo Li, Xiuming Xiao, Shuxia Wang +2
Glass is a liquid that has lost its ability to flow. Why this particular substance undergoes its dramatic slowing down in kinetics while remaining barely distinguishable in structu…
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…
A metasurface with bidirectional hyperbolic surface modes and positionsensing applications
Chuandeng Hu, Xiaoxiao Wu, Rui Tong +5
We theoretically and experimentally studied resonance-induced hyperbolic metasurfaces, proving that it is an efficient way to introduce Fano-resonance and decreasethe Q-factor in o…
Direct Observation of Valley-polarized Topological Edge States in Designer Surface Plasmon Crystals
Xiaoxiao Wu, Yang Meng, Jingxuan Tian +4
The extensive research of two-dimensional layered materials has revealed that valleys, as energy extrema in momentum space, could offer a new degree of freedom for carrying informa…
The Existence of Topological Edge States in Honeycomb Plasmonic Lattices
Li Wang, Ruo-Yang Zhang, Meng Xiao +3
In this paper, we investigate the band properties of 2D honeycomb plasmonic lattices consisting of metallic nanoparticles. By means of the coupled dipole method and quasi-static ap…
Time Circular Birefringence in Time-Dependent Magnetoelectric Media
Ruo-Yang Zhang, Yan-Wang Zhai, Shi-Rong Lin +3
Light traveling in time-dependent media has many extraordinary properties which can be utilized to convert frequency, achieve temporal cloaking, and simulate cosmological phenomena…
Coalescence of Pickering emulsion droplets induced by an electric field
Guo Chen, Peng Tan, Shuyu Chen +3
Combining high-speed photography with electric current measurement, we investigate the electrocoalescence of Pickering emulsion droplets. Under high enough electric field, the orig…
A negative dielectric constant in nano-particle materials under an electric field at very low frequencies
