Optical metasurfaces can unprecedently regulate versatile wavefronts at the subwavelength scale. Most well-established optical metasurfaces are, however, static and feature well-defined optical responses that are determined ...
Metasurfaces are artificial materials designed at the nanoscale, which can control the scattering of light with exceptionally high precision. Over the past decade or so, these materials have been used to create a variety ...
Materials scientists aim to engineer intelligence into the fabric of materials or metamaterials for programmable functions. Engineering efforts can vary from passive to active forms to develop programmable metasurfaces using ...
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. ...
Helical plasmonic nanostructures have attracted considerable attention in materials science and chemistry due to their inherent optical chirality. In a new report, Yang Chen and a research team in the department of Mechanical ...
Researchers at the University of Michigan and City University of New York have recently proposed and experimentally validated a transparent, electronically tunable metasurface. This metasurface, presented in a paper published ...
Metasurfaces are two-dimensional (2-D) metamaterials that can control scattering waves of a light beam. Their applications include thin-sheet polarizers, beam splitters, beam steerers and lenses. These structures can control ...
Holography is a powerful tool that can reconstruct wavefronts of light and combine the fundamental wave properties of amplitude, phase, polarization, wave vector and frequency. Smart multiplexing techniques (multiple signal ...
(Phys.org)—Dynamic holograms allow three-dimensional images to change over time like a movie, but so far these holograms are still being developed. The development of dynamic holograms may now get a boost from recent research ...
