Multiple Orbital Angular Momentum Beams with High‐Purity of Transmission‐Coding Metasurface (Adv. Theory Simul. 4/2023). Issue 4 (12th April 2023) - Liu, Xiaobin
Abstract : Broadband Transmission‐Coding Metasurface with Multi‐Vortex‐Beam In article number 2200842, Si Jia Li and co‐workers develop a new type of transmission‐coding metasurface by changing the size of metal patches based on the principle of propagation phase and phase superposition, which digitally realize the vortex waves with wide‐band, high‐purity, and multiple orbital angular momentum (OAM) beams simultaneously. This transmission‐coding metasurface with multi‐vortex‐beam has potential applications in the OAM multiplexing communication and multi‐target positioning in wireless systems.
