Reflective-type circularly polarized plane hyperlens based on graphene metasurface

摘要: The invention relates to a reflective-type circularly polarized plane hyperlens based on graphene metasurface, and belongs the field of novel artificial electromagnetic materials optical devices. comprises lower metal substrate layer, middle dielectric layer an upper metasurface which is provided with rectangular hole array used for controlling polarization direction propagation characteristic reflected wave. In addition, also controllable bias voltage device connected substrate, so as adjust Fermi energy change conductivity achieve dynamic tunable focusing performance lens. can wideband focusing, easy control. Compared transmission-type too low in transmission efficiency, more suitable actual scene, higher practicality.
