In article number 1900710, He‐Xiu Xu and co‐workers propose a strategy to realize spin‐decoupled high‐capacity multifunctional metasurface by multiplexing the frequency and wavevector degree of freedom. By integrating both geometric and dynamic phases in a split ring resonator and crossbars in achessboard super metaatoms, the inherent limitation of spin‐flipped Pancharatnam–Berry profiles can be completely decoupled between two spin states. Two proof‐of‐concept metadevices are experimentally demonstrated both with the four‐port wavefront manipulations.

复用的超颖表面：通过自旋解耦多通道超颖表面执行的波矢和频率复用（Adv。Mater。Technol。1/2020）

在第1900710号文章中，徐合秀及其同事提出了一种通过复用频率和波矢自由度来实现自旋解耦的高容量多功能超表面的策略。通过将几何相位和动态相位集成在裂环谐振器中和横梁在棋盘超级形而上学，自旋翻转的Pancharatnam–Berry轮廓的固有局限性可以在两个自旋状态之间完全解耦。通过四端口波前操纵，实验证明了两种概念验证元设备。
