Multi‐Channel Wireless Communication Based on Amplitude‐Phase Reconfigurable Space‐Coding Beamforming Metasurface

open access: yesAdvanced Electronic Materials, Volume 10, Issue 8, August 2024.
This work presents an innovative amplitude‐phase reconfigurable metasurface designed to construct a robust multi‐channel wireless communication framework. Notably, the signal is modulated in the spatial domain without involving time modulation. First, it generates desired scattering beams through beamforming to establish multiple channels.
