But even apart from cloaking devices, the metamaterial techniques being studied have other applications, including fiberoptics.

Because the metamaterial is imperfect, the light rays are distorted and interact with each other as they spread.

By contrast, the Duke imaging system used a thin strip of metamaterial mated with some electronics and processing software.
To make the metamaterial, the team worked with cobalt nanoparticles -- which have self assembling qualities -- suspended in kerosene.

If you thought melting gadgets were clever, how about a multiverse-containing metamaterial?

The work not only gives evidence of the potential of self-organisation in metamaterial creation, but could also have implications for the study of new types of optical devices.

In the metamaterial, both arrows flowed in the same direction.

Engineers at Duke University have come up something that falls more into the latter category: a metamaterial imaging sensor that doesn't require a lens to generate a picture.
The imaging system developed by graduate student John Hunt and colleagues at Duke University in North Carolina has no lens and instead combines a metamaterial mask or aperture and complicated mathematics to generate an image of a scene.
According to research published in the most recent issue of Physical Review Letters, ships can be made vastly more efficient by tricking the surrounding water into staying still using a metamaterial that can alter the normal forces of nature.

The key change was the addition of copper strips to the metamaterial that shields an object from incoming light to create a better material, couple with a slight change in its orientation to solve a problem caused by dividing the metamaterial of the cloaking device into quadrants.
