- Abstract
Reconfigurable metasurfaces have emerged as a versatile platform for reshaping the wireless environment into a desirable form at low cost. Despite the rapid growth, most of the existing metasurfaces only support reflection operation or transmission operation, only providing service coverage of backward or forward half‐space when they are used for wireless communications. Here, an intelligent programmable omni‐metasurface integrating reflection mode, transmission mode, and duplex mode of simultaneous reflection and transmission modes in the same polarization and frequency channel is proposed, capable of providing ubiquitous full‐space service coverage for multiuser wireless communication applications. As exemplary demonstrations, a series of dynamic functionalities have been realized, including twin‐beam scanning in reflection mode, twin‐beam scanning in transmission mode, and identical/distinct dynamic beams for both forward and backward half‐spaces in duplex mode, which are customized for signal reflection, transmission, and simultaneous symmetric/asymmetric reflection and transmission in wireless communication scenarios. The proposed tunable omni‐metasurface provides a new method for full‐space wave manipulation, which may offer untapped potentials for real‐time, fast, and sophisticated wave control in applications such as miniaturized systems, integrated photonics, and intelligent communications.
