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 ...

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 ...

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

In essence, calcite splits a beam of light into two dots based on polarization. By aligning filters and rotating angles, you can observe how light behaves when forced into ‘choices’.

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

Just like electromagnetic waves, gravitational waves have a property known as polarization, which can be either right- or left- handed. In other words, the wave can somehow "rotate" clock- or ...

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