Abstract:
Engineered materials composed of designed inclusions can exhibit exotic and unique electromagnetic properties not inherent in the individual constituent components. These artificially structured composites, known as metamaterials, have the potential to fill critical voids in the electromagnetic spectrum where material response is limited and enable the construction of novel devices. Recently, metamaterials that display negative refractive index - a property not found in any known naturally occurring material - have drawn significant scientific interest, underscoring the remarkable potential of metamaterials to facilitate new developments in electromagnetism. © 2006 Elsevier Ltd.
