Gridded "Superlens" Brings Wireless Power Transmission A Step Closer

Above is a close-up of what developers call a "superlens," a device that can focus low-energy magnetic waves over a distance. The result? Wireless power generation over nearly one foot of air between transmitter and receiver.


That might not seem like a great feat, but its Duke University creators say the superlens for the first time demonstrates that electricity can be sent efficiently and safely over a gap larger than either transmitter or receiver.

It's a significant step toward realizing Nikola Tesla's century-old dream of transmitting energy without wires.
