Manipulating light at will - Duke metamaterials strike again
Left-handed metamaterial flat lens consisting of an array of 3 by 20 by 20 unit cells. With a unit cell width of 5 mm, this geometry shows reversed refraction and left-handed focusing properties at microwave frequencies between 10 and 11 GHz. (Image: NASA)
Article Summary
Duke University is on a roll, showing off yet another potentially game-changing property of the exotic man-made substances known as metamaterials. This time the property could have deep consequences for the transmission of information via light. Maybe the most important potential use of all.
