Query: Tailored Optical Polarization in Nano-Structured Metamaterials   A very efficient method for the calculation of the effective optical response
of nano-structured composite systems allows the design of metamaterials
tailored for specific optical polarization properties. We use our method to
design 2D periodic arrays of sub-wavelength dielectric inclusions within
nanometric supported metallic thin films which behave as either an almost
perfect linearly dichroic system, as a controllable source of circular
polarized light, as a system with a large circular dichroism, or as a circular
polarizer. All of these systems may be tuned over a wide energy range.
