Metasurfaces are optically thin metamaterials that can control the wavefront of light completely, although they are primarily used to control the phase of light. In a new report, Adam C. Overvig and colleagues in the departments ...
Physicists and materials scientists have developed a compact optical device containing vertically stacked metasurfaces that can generate microscopic text and full-color holograms for encrypted data storage and color displays. ...
For the first time, researchers have used ultra-thin layers of 2-D structures known as metasurfaces to create holograms that can measure the polarization of light. The new metasurface holograms could be used to create very ...
