Abstract:
The authors study perspectives of nanowire metamaterials for negative-refraction waveguides,
high-performance polarizers, and polarization-sensitive biosensors. They demonstrate that the
behavior of these composites is strongly influenced by the concentration, distribution, and geometry
of the nanowires, derive an analytical description of electromagnetism in anisotropic
nanowire-based metamaterials, and explore the limitations of their approach via three-dimensional
numerical simulations. Finally, they illustrate the developed approach on the examples of
nanowire-based high-energy-density waveguides and nonmagnetic negative-index imaging systems
with far-field resolution of one-sixth of vacuum wavelength.
