Time-varying OAM beams generation by a metasurface

, 2023
We demonstrate the use of a space-time-coding digital metasurface operating in the microwave regime to experimentally generate various modes of time-varying orbital angular momentum (OAM) beams. By developing a time-domain field mapping technique, we are
