I don't really see the breaktrought here. As far as I can see (I'm not an expert), they managed to keep the phase undisturbed. Metamaterials as such aren't exactly new, but certainly very interesting. Wikipedia is very informative on this topic (with a long list of applications): http://en.wikipedia.org/wiki/Metamaterial http://en.wikipedia.org/wiki/Metamaterial More about the cloaking (which there is already some success with): http://en.wikipedia.org/wiki/Metamaterial_cloaking http://en.wikipedia.org/wiki/Metamaterial_cloaking And yeah, the article doesn't seem very professional: > A metamaterial is an artificial material that is engineered to have properties that can’t be found in nature.
