Generation of Mode-Reconfigurable and Frequency-Adjustable OAM Beams Using Dynamic Reflective Metasurface

Recently, much attention has been paid to beams carrying orbital angular momentum (OAM) for radio communication, which faces a great challenge of dynamic generation of OAM with different topological charges. In this paper, a novel reflective metasurface is designed to generate mode-reconfigurable OA...
