Meet the Needle Beam, No More Signal Loss


Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have created an entirely new way to send light beams called the ‘needle beam.‘  They are able to send a beam of light at an unprecedented distance without any loss of information.

While all waves naturally spread, the needle beam, or cosine-Gauss plasmon beam, propagates in incredibly tight confinement along a metallic surface.  The propagation remains so confined that the beam has redefined what researchers believed was mathematically possible.  The discovery will lead to ultra fast communication with little to no loss of signal.

First quantum teleportation, and now the needle beam.  The future just keeps getting faster every day.

Good bye loading-hour-glass… farewell waiting!
