Next Generation Lens Promises More Control

Duke University engineers have created a new generation of lens that could greatly improve the capabilities of telecommunications or radar systems to provide a wide field of view and greater detail. But the lens they fashioned doesn’t look anything like a lens. While traditional lenses are made of [...]

DARPA-Funded Study to Detect Viral Infection Before Symptoms Appear

The Defense Advanced Research Projects Agency (DARPA), the research arm of the U.S. Department of Defense, has awarded Duke University $19.5 million for an effort led by the Duke Institute for Genome Sciences & Policy (IGSP) to design a portable, easy-to-use diagnostic device that can reveal [...]

Room's Ambience Fingerprinted By Cell Phone

DURHAM, N.C. -- Your smart phone may soon be able to know not only that you're at the mall, but whether you're in the jewelry store or the shoe store. Duke University computer engineers have made use of standard cell phone features – accelerometers, cameras and microphones – to turn the unique [...]

Lightning's Mirror Image, Only Much Bigger

DURHAM, N.C. -- With a very lucky shot, Duke University scientists have captured a one-second image and the electrical fingerprint of a huge jolt of lightning that flowed 40 miles upward from the top of an offshore tropical storm. These rarely seen, highly charged meteorological events are known as [...]

Two Young ECE Researchers Awarded Presidential Career Awards

Two Duke University engineers have received the highest honor given to scientists by the U.S. government. Adrienne Stiff-Roberts and Chris Dwyer, both assistant professors of electrical and computer engineering at Duke’s Pratt School of Engineering, each received a Presidential Early Career Award [...]

Writing in Air Is Not Pie in the Sky

It's a familiar scene in airports and train stations. Hands full with luggage, briefcase, laptop or coat and there’s something you need to remember, like the level and row numbers where you parked your car in the deck. What do you do? Instead of relying on your memory, or finding a place to put all [...]

Young Electrical Engineer Honored for Research

When Adrienne Stiff-Roberts decided during her high school career that she wanted to be a scientist, and then an engineer, she didn’t know that she’d end up manipulating the exotic properties of quantum mechanics to perfect devices ranging from infrared cameras to solar cells. It’s not surprising [...]

Next Generation Cloaking Device Demonstrated

A device that can bestow invisibility to an object by “cloaking” it from visual light is closer to reality. After being the first to demonstrate the feasibility of such a device by constructing a prototype in 2006, a team of Duke University engineers have produced a new type of cloaking device, [...]

Tiny Lasers, Big Advances

While an undergraduate in the early 1980s at Creighton University in Omaha, Neb., Nan Jokerst thought lasers were so cool she should build one herself. Using plans from a Scientific American article, she did just that in the basement of the physics building. "It worked, amazingly enough," she says [...]

Harnessing Lightning and Hiding from Sound

Steve Cummer jokingly calls himself something of a Luddite because of his stubborn refusal to give up pencil and paper as his main medium for working through ideas. But in reality, that quirk is hardly enough to justify such a title, particularly when you consider that some of those ideas he [...]
