摘　　要：This paper describes a 3D-printed conformal reconfigurable spin-decoupled metasurface and supports both independent beam shaping and dual-channel reconfigurability.The increasing complexity of metasurface structures and reconfigurable spin-decoupling among conformal structures are rarely reported due to their challenging properties.In this paper,a reconfigurable metasurface based on 3D-printing technology is proposed for reconfigurable spin-decoupled curved structures at 13.5-14.5 GHz.Curved surface spin-decoupling is realized for the first time and verified by simulation and experiment.Beam deflection(20°and 35°)and near-field focusing(100 mm and 150 mm)were achieved at different circularly polarized wave incidences.Switching the beam between the two states was achieved by incorporating the water-based metasurface.As a proof of concept,metasurfaces that have anomalous reflections in both channels were fabricated and measured.Furthermore,reconfigurable spin-decoupling was achieved using a water-based metasurface.This work extends the phase engineering approach in metasurfaces and may have a wide range of applications in communications,sensing,imaging,and camouflage.
