DURHAM, N.C. – Duke University engineers have developed a novel “sensor” that is more efficient, versatile, and cheaper for potential use in such applicationsas airport security scanners, and collision avoidance systems for aircraft cars or maritime vessels.
The researchers fabricated a unique material, known as a metamaterial, that acts as a “lens” to image scenes using fewer components than conventional detectors. Because of the properties of this man-made material, much of... Thursday, 17 January 2013
