Khurram Afridi of Cornell University is pioneering an innovative approach for the wireless charging of electric vehicles and other mobile machines while they remain in motion.

The idea harnesses the power of alternating magnetic fields and addresses related problems by looking to outer space.

"Wireless power transfer is based on the same underlying physics used to send messages through radio waves to spacecraft in deep space, things like Voyager," says Afridi, associate professor of electrical and computer engineering in Cornell's College of Engineering. "Except now we are sending much more energy across much shorter distances, to moving vehicles."

Afridi says he is driven at a fundamental level to bring together "two very different communities — high-frequency electronics and high-power electronics — who have never talked to one another, who don't speak the same language, who essentially solve problems very differently, and merge them together to essentially create an entirely new field and also enable brand new applications."
