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. ©2006 American Institute of Physics

  17. Mathematically, the average area of the unit cell A, in random anisotropic composite is related to the average separation between neighboring elements along the two orthogonal directions l<sub>x-tilde</sub>, and l<sub>y-tilde</sub>, through the metric tensor galphabeta, A=[summation]<sub>{alpha,beta} = {x-tilde,y-tilde}</sub>galphabetalalphalbeta. The tensor becomes diagonal in “eigen” axes {x-tilde,y-tilde}={x,y}, used as primary directions throughout this letter.

  20. The role of parameters chi-hat , used in this work is similar to that of interaction coefficients introduced for Lorentz model in Ref. 20. These two techniques provide identical results for isotropic (in x,y, plane) composites, while Eq. (6) tends to be more robust than Lorentz model when |Lambda|,|Omega|~1.

  22. Note that while S(xi)-->[infinity], in the limit xi-->1, the expression xiS(xi)−S(1/xi)/xi, remains finite for xi=1+Delta, with |Delta|<<1.
