The metasurface is an ultra-thin resonant element with special physical properties. A good example of such an innovation is seen in the thermally based photon-detector project at Duke University, ...

An artistic rendition of how the new ultrafast metasurface works. Mikkelsen’s lab’s approach, called a “metasurface,” uses precisely tailored silver nanocubes placed on a transparent film only 10 ...

Metasurfaces featuring tailored silver nanocubes could allow thermal photodetectors to approach speeds akin to traditional digital cameras. (Nanowerk News) Electrical engineers at Duke University have ...

A closely watched clinical trial in Britain that screened blood for early detection of cancer did not show a reduction in diagnoses at later stages of the disease. By Rebecca Robbins and Gina Kolata A ...

Kidde has become the best-known name in the world of smart smoke detectors—a relatively low bar given how few people know the brand of their smoke detector. Still, you'll find Kidde recommended by ...

In the context of the continuous development of high-speed optical communication, on-chip optical information processing is regarded as the core of next-generation computing architectures. Integrated ...

A metasurface-enhanced thermal photodetector achieves 125 picosecond response times, approaching semiconductor speeds without external power or cooling while retaining broad wavelength flexibility.

Generative artificial intelligence has set off a tremendous amount of excitement, speculation, and anxiety thanks to its ability to convincingly mimic human work, including human writing. Although a ...
