PRINCETON, N.J., Oct. 15, 2007 -- A new, easy-to-produce material created from semiconductors refracts light negatively, bending the waves in the opposite direction from that taken by all materials found in nature. This unique ability may contribute to significant advances in areas including high-speed communications, medical...Read full articleRelated content from Photonics MediaARTICLESLighting up the Lungs to Detect DiseaseA novel imaging tool that rapidly diagnoses bacterial lung infections could help physicians customize antibiotic treatment for patients in intensive care units.
