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…
Unidirectional zero reflection as gauged parity-time symmetry
James Gear, Yong Sun, Shiyi Xiao +5
We introduce here the concept of establishing Parity-time symmetry through a gauge transformation involving a shift of the mirror plane for the Parity operation. The corresponding…
Tailor the functionalities of metasurfaces: From perfect absorption to phase modulation
Che Qu, Shaojie Ma, Jiaming Hao +8
Metasurfaces in metal/insulator/metal configuration have recently been widely used in photonics research, with applications ranging from perfect absorption to phase modulation, but…
Fractal plasmonic metamaterials for subwavelength imaging
Xueqin Huang, Dexin Ye, Shiyi Xiao +4
We show that a metallic plate with fractal-shaped slits can be homogenitized as a plasmonic metamaterial with plasmon frequency dictated by the fractal geometry. Owing to the all-d…
