A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many ...

Researchers use large language models to streamline nanoscopic material design for advanced optical systems like camera lenses and VR headsets. (Nanowerk News) A team of researchers at Penn State have ...

A team of researchers at Penn State have devised a new, streamlined approach to designing metasurfaces, a class of engineered materials that can manipulate light and other forms of electromagnetic ...

We live in a time when our thoughts no longer end where our minds do. Every scroll, post and click ripples outward, merging with millions of others to form invisible currents of belief and emotion.

In the realm of active 3D imaging, the light detection and ranging (LiDAR) technology plays a pivotal role, offering direct depth acquisition and robust resistance to environmental noises. LiDAR ...

Metasurfaces, as 2D artificial electromagnetic materials engineered at subwavelength scales, enable efficient manipulation of electromagnetic waves far beyond natural materials, bridging the gap ...

This paper introduces a broadband polarization conversion reconfigurable metasurface retroreflector, which is made up of periodically arranged, specially engineered broadband polarization conversion ...
