If I can’t be beautiful, I want to be invisible

Invisibility

This quote by Chuck Palahniuk might soon be possible. A team of Scientists led by Xiang Zhang at the UC Berkeley managed to render small objects invisible with the use of so called metamaterials.

The magic word here is negative refraction. In nature there are only materials with a positive refractive index. Until now 3D-metamaterials with negative refraction have only been reported for microwaves.

This week Nature and Science are publishing two articles about metamaterials that work in the near-infrared and visible light range.

Of course we are still far away from a cloaking device á la STAR TREK, but the future comes only one day at a time.
