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.
2011 Daily Tel. (Nexis) 30 Mar. 6 Cloaks that make someone invisible are becoming a real possibility. The secret is creating so-called ‘metamaterials’ that can bend light around an object.
