Tiny metasurface devices could help improve communication, terahertz imaging, manipulating particles and encoding of quantum information Peer-Reviewed Publicationimage: Researchers created metasurface devices for linear polarization multichannel transmission and superposition states of spherical and vortex waves. The new technology could, for example, help ease the transition to faster 6G wireless networks, which will likely be based on high frequency waves such as those in the terahertz region.
