(The Conversation is an independent and nonprofit source of news, analysis and commentary from academic experts.) But things are much less heated at the local level. A survey of more than 1,400 local ...

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 ...

This study addresses the limitations of conventional metasurfaces, which exhibit symmetric electromagnetic responses under forward and backward incidences and are difficult to achieve distinct ...

Because it is anticipated to be a new physical quantity for communication multiplexing and has significant potential for increasing channel capacity and enhancing spectrum resource utilization, ...

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 ...

The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging.
