Metamaterial Definition

mĕtə-mə-tîrē-əl
noun
A usually artificial material that exhibits special properties not normally found in nature, such as a negative index of refraction, in its interaction with electromagnetic radiation, sound, or other wave phenomena. Such properties are a consequence of the metamaterial's structure at the microscopic or macroscopic level, rather than of the underlying properties of its components.
