I’m a big fan of invisibility cloaks, partly cos they’re cool, and partly because I think the principles behind them could end up in a lot of things. Here’s another step forward: Making 3-D objects disappear:
“Making 3-D objects disappear: Ultrathin invisibility cloak created Date: September 17, 2015 Source: DOE/Lawrence Berkeley National Laboratory Summary: Researchers have devised an ultra-thin invisibility ‘skin’ cloak that can conform to the shape of an object and conceal it from detection with visible light. Although this cloak is only microscopic in size, the principles behind the technology should enable it to be scaled-up to conceal macroscopic items as well.”
