Bifunctional metasurface for high-efficiency terahertz absorption and polarization conversion

A reconfigurable metasurface with a switchable function, broad band, high efficiency, and ultra-compact size is crucial for the development of efficient and compact devices. We propose a bifunctional metasurface that utilizes vanadium dioxide (VO 2 ) and graphene to achieve high-efficiency absorptio...
