Fourier Optics on Graphene. (arXiv:1108.5218v1 [physics.optics]):
Using numerical simulations, here we demonstrate that a single sheet of
graphene with properly designed inhomogeneous, nonuniform conductivity
distributions can act as a convex lens for focusing and collimating the
transverse-magnetic (TM) surface Plasmon polariton (SPP) surface wave
propagating along the graphene. Consequently, we show that the graphene can act
as a platform capable of obtaining spatial Fourier transform of infra-red (IR)
SPP signals. This may lead to rebirth of the field of Fourier Optics on a
one-atom-thick structure.
