metamaterial

met·a·ma·te·rial

 (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.

metamaterial

(ˌmɛtəməˈtɪərɪəl)
n
(General Physics) any artificial material created from microscopic arrangements of existing elements in a structure which gives the material unconventional properties, esp when used for cloaking light or sound waves
