In article number 1900472 by Ke Chen, Yijun Feng, and co‐workers, a coding methodology is reported that can enable a metasurface with independent 1‐bit phase codes for orthogonal spins. The proposed method is verified by two spin‐decoupled meta‐devices for either electromagnetic beam deflecting or generating multi‐beams carrying desired orbital angular momentums.
Achieving distinct functionalities for electromagnetic (EM) waves with opposite handedness in a broad frequency range is highly desirable and essential for modern wireless communications and radar stealth. However, available functional meta‐devices still suffer from the issues of locked functionalities or spin‐decoupled properties but with limited bandwidth. Here, a spin‐decoupled coding metasurface...
