Journal ArticleDOI
Anisotropic coding metamaterials and their powerful manipulation of differently polarized terahertz waves
Shuo Liu,Tie Jun Cui,Quan Xu,Di Bao,Liangliang Du,Xiang Wan,Wen Xuan Tang,Chunmei Ouyang,Xiao Yang Zhou,Hao Yuan,Hui Feng Ma,Wei Xiang Jiang,Jiaguang Han,Weili Zhang,Qiang Cheng +14 more
TL;DR: The ability of the anisotropic coding metasurfaces to generate a beam splitter and realize simultaneous anomalous reflections and polarization conversions, thus providing powerful control of differently polarized electromagnetic waves is demonstrated.
Journal ArticleDOI
Convolution Operations on Coding Metasurface to Reach Flexible and Continuous Controls of Terahertz Beams
Shuo Liu,Tie Jun Cui,Lei Zhang,Quan Xu,Qiu Wang,Xiang Wan,Jian Qiang Gu,Wen Xuan Tang,Mei Qing Qi,Jiaguang Han,Weili Zhang,Xiao Yang Zhou,Qiang Cheng +12 more
TL;DR: This study demonstrates that the scattering patterns that are directly calculated from the coding pattern using the Fourier transform have excellent agreements to the numerical simulations based on realistic coding structures, providing an efficient method in optimizing coding patterns to achieve predesigned scattering beams.
Journal ArticleDOI
Reflective chiral meta-holography: multiplexing holograms for circularly polarized waves
Qiu Wang,Eric Plum,Quanlong Yang,Xueqian Zhang,Quan Xu,Yuehong Xu,Jiaguang Han,Weili Zhang,Weili Zhang +8 more
TL;DR: This work demonstrates how planar chirality enables the fully independent realization of high-efficiency meta-holograms for one circular polarization or the other, and shows how to combine different functionalities for left- and right-handed polarized light into a single device, and could lead to new holographic imaging applications.
Journal ArticleDOI
Anomalous Refraction and Nondiffractive Bessel-Beam Generation of Terahertz Waves through Transmission-Type Coding Metasurfaces
Shuo Liu,Ahsan Noor,Liang Liang Du,Lei Zhang,Quan Xu,Kang Luan,Tian Qi Wang,Zhen Tian,Wen Xuan Tang,Jiaguang Han,Weili Zhang,Xiao Yang Zhou,Qiang Cheng,Tie Jun Cui +13 more
TL;DR: In this paper, a transmission-type coding metasurface is proposed to bend normally incident terahertz beams in anomalous directions and generate nondiffractive Bessel beams in normal and oblique directions.
