Anti-mirror optical illusion could increase LED luminosity and laser power
Transform a ball into a rock -- or make it invisible -- using transformation optics
Scientists create first free-standing 3-D cloak
Researchers in the US have, for the first time, cloaked a three-dimensional object standing in free space, bringing the much-talked-about invisibility cloak one step closer to reality.
New 'thermal' approach to invisibility cloaking hides heat to enhance technology
In a new approach to invisibility cloaking, a team of French researchers has proposed isolating or cloaking objects from sources of heatessentially "thermal cloaking." This method, which the researchers ...
Metamaterials and transformation optics control light on a microchip
Using a combination of the new tools of metamaterials and transformation optics, engineers at Penn State University have developed designs for miniaturized optical devices that can be used in chip-based optical ...
