Summary: In this article, a novel broadband dual-polarized reflective metasurface is proposed to enable the multiplexing of orbital angular momentum (OAM) and polarization in the terahertz (THz) region. The metasurface can generate two coaxially propagating OAM beams with distinct modes for each polarization. A THz wireless communication system was demonstrated using the metasurface, achieving an aggregate 48 Gbit/s data transmission with a low bit error rate (BER) below 3.8e-3. This work showcases the feasibility of using metasurfaces for multidimensional multiplexing in ultrahigh-speed THz communication systems.

Summary: A multifunctional metasurface based on graphene and vanadium dioxide (VO2) is designed in this study to function as a broadband absorber, half-wave plate (HWP), and quarter-wave plate (QWP) in the terahertz frequency band. When VO2 is in the metal phase, the metasurface operates as a broadband absorber. When VO2 is in the insulated phase, the metasurface can switch between HWP and QWP by adjusting the Fermi energy of graphene.
