However, most existing metasurfaces are confined to single-wavefront manipulation, which substantially restricts their potential for multifunctional integration and large-capacity communications. To overcome these limitations, we propose a polarization-multiplexed THz reflection metasurface based on an array of metal elliptical patch unit cells for multi-wavefront shaping. By independently adjusting the long- and short-axis dimensions of the elliptical unit cell, full 2π phase coverage with high reflection efficiency is achieved under x - and y -polarized incidence, enabling effective linear polarization (LP) multiplexing. As a proof of concept, we use these unit cells to construct three distinct THz reflective metasurfaces for respectively generating deflected beams (DBs) with different angles, focused beams (FBs) with varied focal lengths, and deflection-focusing beams (DFBs) with different deflection angels and focal lengths for x - and y -polarized illumination. Therefore, the proposed design provides an versatile platform for compact and multifunctional THz devices, indicating significant potential for applications in large-capacity communication and high-density integration systems. terahertz metasurfaces polarization multiplexing and wavefront shaping Full Text Additional Declarations No competing interests reported.
