Metamaterials manipulate light on a microchip
UNIVERSITY PARK, Pa. – Controlling light on a microchip is no easy feat, but new theoretical designs for miniaturized optical devices made of metamaterials could make it a little easier. A unified theory from researchers at Penn State University combines metamaterials and transformation optics. Transformation optics (TO) uses refraction in a rigorously mathematical way by applying the 150-year-old Maxwell equations describing the propagation of light onto metamaterials – artificial constructs with custom-desi...
