Wilkinson. Tea is served from 6pm 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 light in ways
that were orignially not thought to be possible. These materials
are composed of subwavelength electromagnetic structures place
very close to one another. Due to mutual coupling between the
individual structures, they present properties to incident
electromagnetic radiation (such as light) that are different
from those associated with the material from which the
structures are comprised of. In this talk we use periodic arrays
of multiwalled carbon nanotubes as subwavelength structures to
produce optical metamaterials that e
