CONTACT:Tim Wilkinson
DESCRIPTION:Metamaterials are artificial materials with properties that do
  not exist normally in nature. Advances in nanoscale fabrication allow for
  the realization of optical metamaterials which allow us to manipulate lig
 ht in ways that were orignially not thought to be possible.  These materia
 ls are composed of subwavelength electromagnetic structures place very clo
 se to one another. Due to mutual coupling between the individual structure
 s\, they present properties to incident electromagnetic radiation (such as
  light) that are different from those associated with the material from wh
 ich the structures are comprised of. In this talk we use periodic arrays o
 f multiwalled carbon nanotubes as subwavelength structures to produce opti
 cal metamaterials that exhibit artificial dielectric properties and band g
 aps within the optical regime.
