Tunable Airy beams with controllable propagation trajectories have sparked interest in various fields,such as optical ma-nipulation and laser fabrication.Existing research approaches encounter challenges related to insufficient compactness and integration feasibility,or they require enhanced tunability to enable real-time dynamic manipulation of the propaga-tion trajectory.In this work,we present a novel method that utilizes a dual metasurface system to surpass these limita-tions,significantly enhancing the practical potential of the Airy beam.Our approach involves encoding a cubic phase pro-file and two off-axis Fresnel lens phase profiles across the two metasurfaces.The validity of the proposed strategy has been confirmed through simulation and experimental results.The proposed meta-device addresses the existing limita-tions and lays the foundation for broadening the applicability of Airy beams across diverse domains,encompassing light-sheet microscopy,laser fabrication,optical tweezers,etc.
