Anisotropic metamaterials for unique applications

August 18, 2015 @ 4:00 pm - 7:00 pm

Anisotropic nanostructures such as columnar thin films or anodic
nanoporous alumina  can be organized to yield metamaterials with highly
anisotropic material tensors. In fact, using plasmonic nanostructures, the
anisotropic can be so extreme that the dispersion of light can become
hyperbolic.  Gratings containing slanted plasmonic nanocolumns that behave
as  unidirectional surface plasmon couplers and  nanoporous microtubes
with plasmonically filled  nanopores that act as cylindrically anisotropic
optical fibers are newly developed examples of anisotropic metamaterials
that will be discussed in this lecture.
