Anomalous three dimensional refraction in the microwave region by ultra thin high efficiency metalen

Video abstract for the article ‘Anomalous three-dimensional refraction in the microwave region by ultra-thin high efficiency metalens with phase discontinuities in orthogonal directions‘ Recent years have witnessed a great surge of interest in metasurfaces providing phase-discontinuities, which find novel applications in flat lenses, spin–orbit manipulation, wavefront engineering, information processing, holography, etc. Compared to commercially available lensing devices or conventional...
