Engineers give invisibility cloaks a slimmer design

Researchers have designed a new cloaking device that overcomes some of the limitations of existing ‘invisibility cloaks.’ In a new study, electrical engineers have designed a cloaking device that is both thin and does not alter the brightness of light around a hidden object. The technology behind this cloak will have more applications than invisibility, such as concentrating solar energy and increasing signal speed in optical communications. —> Read More
