It, um, looks like we’re getting close to a working cloaking device.
Physicists get ever closer to a Harry Potter-style invisibility cloak with a new, less-bulky metascreen that scatters nano-particles. “Moving forward, one of the key challenges for the researchers will be to use ‘mantle cloaking’ to hide an object from visible light.”
“Whilst previous cloaking studies have used metamaterials to divert, or bend, the incoming waves around an object, this new method, which the researchers dub ‘mantle cloaking’, uses an ultrathin metallic metascreen to cancel out the waves as they are scattered off the cloaked object.”
