How To Make Human-Sized Invisibility Cloaks

Thanks to a new printing method, we are now able to produce large sheets of metamaterials, a new class of materials that is designed to interact with light much differently than natural materials can. Metamaterials are made up of intricately patterned layers, often made of…you guessed it, metals.

The patterns must be on the same scale as the wavelength of the light they’re designed to interact with and must be of nano-size. Although researchers have been able to make invisibility sheets in the past, they were so small that it wasn’t a practical cloak, until now.
