Airy Beam Generation: Approaching Ideal Efficiency and Ultra Wideband with Reflective and Transmissive Metasurfaces

Airy beams are essential for photonic applications, owing to their intriguing diffraction‐free, self‐accelerating, and self‐healing properties. Recently, 2D metasurfaces have offered great opportunities for generating Airy beams within subwavelength thickness. However, they suffer from the bottlenec...
