The development of compact lightweight analogue edge detecting image processors is of particular interest for remote sensing applications such as environmental monitoring and surveillance, due to its ...

Xingjie Ni, left, associate professor of electrical engineering, displays a camera sensor integrated with a three-millimeter-by-three-millimeter metasurface. The metasurface turns a conventional ...

Researchers built a fingernail-sized magnetometer using metasurfaces that measures fields billions of times weaker than Earth's, opening new paths for quantum sensing. At the heart of the sensor is an ...

Learn how researchers combine quantum dots and meta surfaces on CMOS to make smaller SWIR sensors with flexible spectral ...

Proposed device outlines new paths forward for compact ultra-sensitive optical sensors, multi-band switches with high modulation depth, and efficient slow-light modules.

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

(a) and (b) show the photograph and SEM images of the prepared metasurface sample, respectively. (c) Measured specular and integral reflectance spectra of the metasurface in 0.8~1.6 μm. (d) The ...

Researchers have developed a metasurface device that can display three types of images depending on the illumination light. The three-channel device could be used as an anticounterfeiting measure or ...
