TL;DR: Huang et al. as mentioned in this paper developed ultrathin plasmonic metasurfaces to provide 3D optical holographic image reconstruction in the visible and near-infrared regions for circularly polarized light.

TL;DR: A counter-intuitive dual-polarity flat lens based on helicity-dependent phase discontinuities for circularly polarized light is experimentally demonstrated by controlling the helicity of the input light, and the positive and negative polarity are interchangeable in one identical flat lens.

TL;DR: The proposed reprogrammable hologram may be a key in enabling future intelligent devices with reconfigurable and programmable functionalities that may lead to advances in a variety of applications such as microscopy, display, security, data storage, and information processing.

TL;DR: This work expands the visible color space through spatially mixing and adjusting the nanoscale spacing of discrete nanostructures to pave the way toward a new generation of low-cost, high-resolution, plasmonic color printing with direct applications in security tagging, cryptography, and information storage.

TL;DR: In this article, a subwavelength reconfigurable Huygens' metasurface realized by loading it with controllable active elements is presented, which offers unprecedented potentials for real-time, fast, and sophisticated electromagnetic wave manipulation such as dynamic holography, focusing, beam shaping/steering, imaging, and active emission control.
