Programmable metasurface generates dozens of holograms at once
Over the past few decades, engineers have developed various devices that can create holograms, three-dimensional (3D) or ...
The systematic framework for the proposed multi-liquid identification is depicted in Fig. 1. The system comprises a space-time-coding metasurface illuminated by a feeding pyramidal horn antenna, a ...
In a paper, titled "Electrically tunable space-time metasurfaces at optical frequencies," published in the journal Nature Nanotechnology, a team of Caltech engineers reports building such a ...
An article in Opto-Electronic Advances, discusses complete-basis-reprogrammable coding metasurface for generating dynamically-controlled holograms under arbitrary polarization states. This article ...
