Cloak of invisibility almost invented!

I woke up to some pretty epic news today: Germans are one step closer to making a cloak of invisibility! Awesome!! My mind started running rampant with all the insane things that could be done once this thing has been invented. However as I continued to read on, it was clear that we’re still far away from realizing this fairy-tale dream.

Researchers at Germany’s Karlsruhe Institute of Technology report they were able to cloak a tiny bump in a layer of gold, preventing its detection at nearly visible infrared frequencies.

Their cloaking device also worked in three dimensions, while previously developed cloaks worked in two dimensions, lead researcher Tolga Ergin said.

The cloak is a structure of crystals with air spaces in between, sort of like a woodpile, that bends light, hiding the bump in the gold later beneath, the researchers reported in Thursday’s online edition of the journal Science.
