From the Lycurgus cup to H. G. Wells's "Invisible Man," there has always been a fine line between fiction and reality when talking about the possibility to manipulate light and obtain invisibility.

Realizing the world's first cloak of invisibility for a three-dimensional object, Engineering Professor Andrea Alú explains how the discovery of metamaterials is pushing technology beyond conventional limits, producing vastly new opportunities beyond what nature can offer.
This emerging technology offers extensive applications in bioscience, energy, defense, and plenty more we can only imagine from here.
