A switchable and tunable multifunctional terahertz polarization converter based on a graphene metasurface

Abstract

The proposed metasurfaces, enabling polarization conversion and circular dichroism, offer potential for application in waveplate designs and biosensing implementations.

Tunable and switchable multifunctional terahertz meta-mirror based on graphene and vanadium dioxide

“…19 Zhang et al proposed a terahertz metasurface that enables linear polarization conversion and circular dichroism. 20 In addition, in the latest study, Du et al designed a multilayer spin-multiplexing reflective metasurface that introduces a propagation phase and geometric phases in the structure, enabling multichannel holographic imaging in the terahertz band. 21 Guo et al proposed a spin-selective metasurface based on the phase change property of vanadium dioxide that enables multichannel switchable OAMs, paving a new road for multichannel imaging and information encryption.…”
