German scientists have created a three-dimensional "invisibility cloak" that can hide objects by bending light waves.
The findings, published in the journal Science on Thursday, could in the future make it possible to make large objects invisible, but for now the researchers said they were not keen to speculate on possible applications.
This is an excellent example of some of the potential applications of the newly emerging field of metamaterials. To read the rest of the article, click here.
