from The American Heritage® Dictionary of the English Language, 5th Edition.

  • 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.

  • noun engineering , (physics) any material that obtains its electromagnetic properties from its structure rather than from its chemical composition; especially a material engineered to have features of a size less than that of the wavelength of a class of electromagnetic radiation
