Non-Hermitian exceptional physics in RP^2 hyperbolic media
Shengyu Hu, Zhiwei Guo, Wenwei Liu +2
Conventional momentum space provides an orientable base space of a torus for topological classifications based on band theory. Here, we introduce a non-orientable momentum space is…
Generating Spatial Spectrum with Metasurfaces
Wenwei Liu, Zhancheng Li, Hua Cheng +5
Fourier optics, the principle of using Fourier Transformation to understand the functionalities of optical elements, lies at the heart of modern optics, and has been widely applied…
Momentum Analysis for Metasurfaces
Wenwei Liu, Zhancheng Li, Hua Cheng +2
Utilizing discrete phase distribution to fit continuous phase distribution has been a primary routine for designing metasurfaces. In the existing method, the validation of the disc…
Full control of polarization states and phase distributions of light with dual-metasurfaces
Jianxiong Li, Shuqi Chen, Haifang Yang +5
Control of the phase and polarization states of light is an important goal for nearly all optical research. The development of an efficient optical component that allows the simult…
