Recent Progress in Reconfigurable and Intelligent Metasurfaces: A Comprehensive Review of Tuning Mechanisms, Hardware Designs, and Applications (Adv. Sci. 33/2022)

Reconfigurable and Intelligent Metasurfaces In article number 2203747 the recent progress of intelligent metasurfaces, focusing on tuning mechanisms, hardware designs, and applications, is presented. Yejun He and co‐workers discuss the reconfigurable and programmable metasurfaces, classified as space‐gradient, time‐modulated, and space‐time modulated metasurfaces. In addition, the authors provide an overview of the emerging research direction of reconfigurable intelligent surfaces. [Image: see text]
