Antennas receive and transmit electromagnetic waves, delivering information to our radios, televisions, cellphones and more.

This study was published in Optica. Polarization—the orientation of light waves—is a cornerstone of modern technology, critical in everything from next-generation wireless communications to ...

New metasurfaces with nanoantennas could replace lenses and enhance AR, VR, LiDAR, and more by precisely controlling light.

"Accurate control of the polarization state of terahertz ... are nearly three orders of magnitude longer than visible light, terahertz waves place very high demands on the materials and structures ...

The MiFly system enables a drone to determine its precise position space — including its six degrees of freedom — in indoor, ...

Researchers have developed a novel metasurface-based method to generate terahertz complex vector light fields using surface ...

If you want to know the 3D structure of the corona, its density, and how it changes over time—you have to find out where those light waves came from. You do that by measuring the polarization of ...
