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 [...]

Creating the Future of Mobile Computing

Like most users, Romit Roy Choudhury enjoys the freedom, information, and options his iPhone and other devices provide, but for him these instruments serve a more important role as research tools that help him envision future innovations in mobile computing. Roy Choudhury's academic life is [...]

A New Paradigm in Electrical Sensing

When a snake is cut in half, it dies. This illustrates how electrical devices can respond to damage. Since they are at their core closed circuits, devices will fail whenever the circuit is interrupted. However, if these devices could be more like earthworms, intriguing new possibilities arise. [...]

Senior Wins Marshall Scholarship

Dan Roberts, a Pratt School of Engineering student involved in research that created such unconventional electromagnetic devices as an "invisibility cloak" will receive one of 40 Marshall Scholarships offered for the 2009-10 academic year. Roberts, a senior from Melville, N.Y., is the 19th Marshall [...]

Searching for Genes, Photo Files, and Landmines — In Haystacks

Lawrence Carin's graduate training was in electromagnetics and wave analysis-- a fitting choice for someone who remembers trying to assemble and plug in electronic contraptions as a five year old and who grew up tinkering with radios and motors. Overall, his life was fairly standard preparation for [...]

Marine Mammals Sounding Off

Three weeks spent traveling the crystal clear waters of the Caribbean may sound like a vacation, but for Douglas Nowacek, it's part of the job. Nowacek, a new marine biologist at Duke, spends about two months out of the year on such research cruises. Still, he claims that his work isn't necessarily [...]

Adrienne Stiff-Roberts: Putting Artificial Atoms to Use

Adrienne Stiff-Roberts says she didn't do so well as an undergraduate physics student tackling quantum mechanics. "It's one of those topics where, the first time you see it, it's really mind blowing," she says. And yet, today her entire research program is focused on putting the wonders of quantum [...]

David Smith: Creating New Materials that Go Beyond Nature

In 1967, Russian scientist Victor Veselago published theoretical research on a bizarre type of material that, while possible according to the known laws of physics, didn't exist anywhere on the planet as far as anyone could tell. Veselago was describing materials with a negative refraction, which [...]
