Multi‐Dimensional Wave Manipulation via Derived Jones Matrix of Single‐Layer Diatomic Metasurfaces

ABSTRACT In this work, a multi‐dimensional manipulation regime that enables deterministic mappings between structural parameters and electromagnetic responses is developed by utilizing Jones matrix derived from the subunits designed in a single‐layer diatomic system. This regime provides a theoretical framework for structural optimization and wavefront engineering, reducing dependence on parameter scanning and optimization process in empirical trial‐and‐error methods, and offering a more flexible solution for beam manipulation of single‐layer metasurfaces. Through rational structural arrangement, independent/joint amplitude‐phase regulation is achieved across co‐ and cross‐polarized channels, applicable to left‐handed/right‐handed circularly polarized (LCP/RCP) and x/y ‐linearly polarized ( x/y ‐LP) waves. To demonstrate the multi‐degree‐of‐freedom wave regulation capability, metasurfaces are designed and configured with independent amplitude/phase and joint amplitude‐phase coding sequence for near‐field and holographic imaging, customizable focusing and beam steering, etc., among which the beam steering function is experimentally verified. This diatomic metasurface system demonstrates multi‐degree‐of‐freedom manipulation within a single‐layer structure, offering significant potential for developing miniaturized, high‐capacity devices in optical imaging systems, multichannel wireless communications, and advanced sensing applications.
