Each side of each constituent cube of the “superlens” is set with a long, spiraling copper coil. The end of each coil is connected to its twin on the reverse side of the wall. Credit courtesy of Guy Lipworth, graduate student researcher at Duke University

This small copper coil and its twin were used in the experiment to send and receive power using electromagnetic fields. In the background is the metamaterial “superlens” that dramatically increased the power transfer’s range.

A closer look at the metamaterial “superlens” that beams electromagnetic fields to increase the range of wireless power transfers. The squares are actually long coils of copper wire reminiscent of the surface of a microchip. Credit courtesy of Duke University

A side view of the metamaterial “superlens.” Both its width and thickness affects how far it can boost the wireless transfer of power using electromagnetic fields. Credit courtesy of Duke University
