Proposed metamaterial could have a wide range of applications, from sensing to stealth technology

Metamaterials are a type of artificial material which, as the prefix "meta"—meaning in Greek "after" or "beyond"—indicates, demonstrate electromagnetic properties and other characteristics not found in nature.
