Origin: Formed within English, by derivation. Etymons: meta- prefix, material n.

Etymology: < meta- prefix + material n.

Materials Science.

A synthetic composite material engineered to display properties not usually found in natural materials.A particular focus of research has been to create metamaterials with a negative refractive index.

2000 AScribe Newswire (Nexis) 21 Mar. The composite..was produced from a series of thin copper rings and ordinary copper wire strung parallel to the rings. It is an example of a new class of materials scientists call ‘metamaterials’.

2004 Science 19 Nov. 1255/1 Metamaterials that are engineered to exhibit negative indices of refraction can provide a number of advantages in optics, such as the fabrication of a ‘perfect’ lens.
