metamaterial


met·a·ma·te·rial

M5263050 (mĕt′ə-mə-tîr′ē-əl)n. 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.
