Experimental observation of anomalous optical transmission in interlaced metallic wire meshes
Weijie Dong, Xiaoxi Zhou, Xinyang Pan +4
In conventional plasmonic media and plasmonic metamaterials, such as metallic wire mesh, longitudinal mode of electromagnetic wave manifests itself in frequency overlapping transve…
Observation of Higher-Order Topological States in Acoustic Twisted Moiré Superlattice
Shi-Qiao Wu, Zhi-Kang Lin, Bin Jiang +3
Twisted moiré superlattices (TMSs) are fascinating materials with exotic physical properties. Despite tremendous studies on electronic, photonic and phononic TMSs, it has never bee…
Observation of non-Abelian topological semimetals and their phase transitions
Bin Jiang, Adrien Bouhon, Zhi-Kang Lin +5
Topological phases of matter lie at the heart of physics, connecting elegant mathematical principles to real materials that are believed to shape future electronic and quantum comp…
Twisted quadrupole topological photonic crystals
Xiaoxi Zhou, Zhi-Kang Lin, Weixin Lu +3
Topological manipulation of waves is at the heart of the cutting-edge metamaterial researches. Quadrupole topological insulators were recently discovered in two-dimensional (2D) fl…
Arbitrary order exceptional point induced by photonic spin-orbit interaction in coupled resonators
Shubo Wang, Bo Hou, Weixin Lu +3
Many novel properties of non-Hermitian systems are found at or near the exceptional points-branch points of complex energy surfaces at which eigenvalues and eigenvectors coalesce.…
Broadband microwave absorption by logarithmic spiral metasurface
Shubo Wang, Bo Hou, C. T. Chan
We propose to use logarithmic spiral resonators for efficient absorption of microwaves. By combining their scale invariant geometries and Fabry-Perot-type resonances stemming from…
Broadband perfect absorption of ultrathin conductive films with coherent illumination:Superabsorption of microwave radiation
Sucheng Li, Jie Luo, Shahzad Anwar +7
Absorption of microwave by metallic conductors is exclusively inefficient, though being natively broadband, due to the huge impedance mismatch between metal and free space. Reducin…
A unified theory for perfect absorption in ultra-thin absorptive films with constant tangential electric or magnetic fields
Jie Luo, Sucheng Li, Bo Hou +1
The maximal absorption rate of ultra-thin films is 50% under the condition that the tangential electric (or magnetic) field is almost constant across the film in symmetrical enviro…
Transformation optics with Fabry-Pérot resonances
M. M. Sadeghi, Sucheng Li, Lin Xu +2
Transformation optics is a powerful tool to design various novel devices, such as invisibility cloak. Fantastic effects from this technique are usually accompanied with singular ma…
Deep Subwavelength Electromagnetic Transparency through Dual Metallic Gratings with Ultranarrow Slits
Chunyin Qiu, Sucheng Li, Ruirui Chen +3
In this Letter, we study the transmission response of microwaves through two identical metallic plates machined with ultranarrow slit arrays. The measured and calculated transmissi…
Realizing bending waveguides with anisotropic epsilon-near-zero metamaterials
Jie Luo, Ping Xu, Huanyang Chen +2
We study metamaterials with an anisotropic effective permittivity tensor in which one component is near zero. We find that such an anisotropic metamaterial can be used to control w…
