All communications networks need some form of multiplexing -- the ability to send multiple data streams through a single medium. Researchers from Brown University have used a leaky wave antenna to separate terahertz waves by frequency. The work, which was published in Nature Photonics, provides a viable multiplexing and demultiplexing strategy for future terahertz data networks.
Terahertz radiation could one day provide the backbone for wireless systems that can deliver data up to one hundred times faster than today's cellular or Wi-Fi networks.
