Experimental Demonstration of Controllable PT and anti-PT Coupling in a non-Hermitian Metamaterial
Chang Li, Ruisheng Yang, Xinchao Huang +3
Non-Hermiticity has recently emerged as a rapidly developing field due to its exotic characteristics related to open systems, where the dissipation plays a critical role. In the pr…
Highly degenerate photonic flat bands arising from complete graph configurations
Hanyu Wang, Biao Yang, Wei Xu +4
Inspired by complete graph theory, we demonstrate that a metallic claw "meta-atom" structure can carry a high number of nearly degenerate resonant modes. A photonic meta-crystal co…
Controlling the toroidal excitations in metamaterials for high-Q response
Yuancheng Fan, Fuli Zhang, Quanhong Fu +2
The excitation of toroidal multipoles in metamaterials was investigated for high-Q response at a subwavelength scale. In this study, we explored the optimization of toroidal excita…
A metamaterial modulator based on electrically controllable electromagnetically induced transparency
Yuancheng Fan, Tong Qiao, Fuli Zhang +3
Electromagnetically induced transparency (EIT) is a promising technology for the enhancement of light-matter interactions, and recent demonstrations of the quantum EIT realized in…
Tunable mid-infrared coherent perfect absorption in a graphene meta-surface
Yuancheng Fan, Zhe Liu, Fuli Zhang +6
We exploited graphene nanoribbons based meta-surface to realize coherent perfect absorption (CPA) in the mid-infrared regime. It was shown that quasi-CPA frequencies, at which CPA…
Dynamically tunable Fano resonance in periodically asymmetric graphene nanodisk pair
Zhengren Zhang, Xiaopeng Su, Yuancheng Fan +3
We present a dynamically frequency tunable Fano resonance planar device composed of periodically asymmetric graphene nanodisk pair for the mid-infrared region. There are two kinds…
