The breakthrough’s goofy name comes from the fact that it is made of both an antenna and a rectifier diode. The technology is simple, efficient, and has the potential to completely change the way […]

The new technique has been invented by Brian Willis, an associate professor of chemical and biomolecular engineering at the University of Connecticut and the former director of UConn’s Chemical Engineering Program. He explored the so called rectennas, or nano-antennas, […]
