Novel Sensor Provides Bigger Picture
18 January 2013
Duke University engineers have developed a novel “sensor” that is more efficient, versatile, and cheaper for potential use in such applications as airport security scanners, and collision avoidance systems for aircraft, cars or maritime vessels. Read more.
Hiding in Plain Sight
18 November 2012
Invisibility is an illusion, a way of manipulating light so that a hidden object cannot be perceived. In the same way that magicians use mirrors to make things disappear, we can now use metamaterials. In a recent editorial piece published in the Gray Matter section of the Sunday edition of the New York Times, David Smith and Nathan Landy provide a perspective on the parallels of achieving invisibility through magic and through science. Read the article here.

7 November 2009
The Duke "invisibility cloak" was featured on Wallace and Gromit's World of Invention, a BBC series highlighting inventors and invention. Sir John Pendry is interviewed about the conception and operation of the cloak on the episode "Come to Your Senses," which aired on BBC1 at 7:30 pm, November 24.
Smith Selected by Thomson Reuters as a Citation Laureate for 2009
24 September 2009
David R. Smith, along with Sir John Pendry from Imperial College and Sheldon Schultz from U. C. San Diego, have been selected among the twenty-five "Thomson Reuters Citation Laureates" for 2009. The Citation Laureates are recognized for their contribution to the advancement of science. Since 2002, 15 Citation Laureates have gone on to win Nobel Prizes. The Citation Laureates typically rank among the top one-tenth of one percent of researchers in their fields, based on citations of their published papers over the last two or three decades.
Transformation Optics for Reducing Lens Profile
5 September 2009
In a paper published in Optics Express (September 14, 2009 issue), Dan Roberts and co-authors illustrate the use of the transformation optical approach to reduce the profile of a lens or other optical device. Though the gradient index materials specified by the transformation may render the reduction difficult to achieve in practice, the results nevertheless show the potential of applying the transformation optical technique to improve conventional devices in unconventional ways.
Transformation Optics MURI Awarded
20 June 2009
A joint team led by Duke University has been awarded a Multiple University Research Initiative on the topic of Transformation Optics. The award is sponsored by the Army Research Office (ARO), and includes team members from Purdue University, UC Berkeley, NC State University and Imperial College, London.
Electromagnetic source transformations: Cover story in Applied Physics Letters
11 May 2009
Transformation optics can be used to design media with unique properties for the manipulation of electromagnetic waves. The transformation optical approach can be used not only to control the path of light, but also to change the way that currents and charges (or sources) behave when they interact with light. The interaction of electromagnetic waves is fundamental in the design of antennas. In the latest issue of Applied Physics Letters, Jeffery Allen and colleagues demonstrate several examples of transforming space in the presence of sources to make interesting radiating structures.
Dan Roberts wins Hertz Fellowship for postgraduate study in the physical sciences
11 May 2009
Dan Roberts was awarded a Fannie and John Hertz Foundation Fellowship. The Hertz Fellowship is merit based and widely considered to be one of the most prestigious graduate fellowships awarded. The fellowship provides approximately $250,000 of support over a five year tenure. One of the goals is to provide financial independence for fellows, allowing them to pursue innovative research as per their own interests. Dan will defer his fellowship for two years to study in the UK as a Marshall Scholar.

Broadband cloaking with new metamaterial structure
15 January 2009
Our most recent experiment confirms that objects on a mirror--or ground plane--can be hidden from detection by a metamaterial 'cloak.' The latest work, based on a theoretical prediction by Li and Pendry, illustrates some of the progress that has been achieved over the last two years of research (published in Science, January 16, 2009).
