  ABSTRACT: This study addresses the limitations of conventional metasurfaces, which exhibit symmetric electromagnetic responses under forward and backward incidences and are difficult to achieve distinct functionalities and wavefront control. A multi-layer metasurface based on a polarization-ordered binary double-sided design is proposed. By breaking spatial symmetry at the structural level, diode-like asymmetric transmission and independent wavefront control are achieved. The design adopts a checkerboard-like staggered arrangement of unit cells, enabling different functionalities under forward and backward incidences for the same polarized wave. Orthogonal polarization conversion and broadband phase coverage are realized using multi-layer twisted metallic structures and a grating layer. Simulation results demonstrate that the metasurface achieves a - 30° beam deflection under forward incidence, while generating a vortex beam with topological charge 1 under backward incidence. The two channels exhibit good isolation, along with broadband and high transmission efficiency characteristics. This research provides new insights for high-performance non-reciprocal devices, bidirectional multi-functional integrated antennas, and information-encryption surfaces.
