Abstract
In this paper, an ultrathin dual-polarized Huygens' metasurface is proposed to achieve 360° phase control with high transmission. Based on this element, a dual-polarized transmissive metasurface antenna is designed to generate multi-mode vortex waves propagating coaxially in shared apertures in terahertz regime. Simulation results show that this method can be a promising solution for combining OAM multiplexing and polarization multiplexing for terahertz wireless communications.
