Perfect anomalous reflectors at optical frequencies
Tao He, Tong Liu, Shiyi Xiao +4
Reflecting light to a pre-determined non-specular direction is an important ability of metasurfaces, which is the basis for a wide range of applications (e.g., beam steering/splitt…
Bloch oscillations and subwavelength focusing in stacked fishnet metamaterials
Xiaopeng Su, Zhijie Gong, Hongrui Wu +4
In this letter, we introduce stacked fishnet metamaterial for steering light in microwave region. We numerically demonstrate that optical Bloch oscillations and a focus of as small…
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…
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…
Tunable terahertz coherent perfect absorption in a monolayer graphene
Yuancheng Fan, Fuli Zhang, Qian Zhao +2
Coherent perfect absorber (CPA) was proposed as the time-reversed counterpart to laser: a resonator containing lossy medium instead of gain medium can absorb the coherent optical f…
Photonic band gap of a graphene-embedded quarter-wave stack
Yuancheng Fan, Zeyong Wei, Hongqiang Li +2
Here, we present a mechanism for tailoring the photonic band structure of a quarter-wave stack without changing its physical periods by embedding conductive sheets. Graphene is uti…
