具有极端光学各向异性的纳米线材料

Nanowire metamaterials with extreme optical anisotropy

Justin Elser, Robyn Wangberg, Viktor A. Podolskiy, Evgenii E. Narimanov

摘要:

我们研究了纳米线超材料在负折射波导、高性能偏振器和偏振敏感生物传感器方面的应用前景。我们证明了这些复合材料的行为受到纳米线的浓度,分布和几何形状的强烈影响,推导出基于各向异性纳米线的超材料中电磁的解析描述,并通过三维数值模拟探索我们方法的局限性。最后,我们举例说明了开发的方法上的例子,基于石英的高能量密度波导和非磁性负折射率成像系统的远场分辨率的六分之一的真空波长。

英文摘要:

We study perspectives of nanowire metamaterials for negative-refraction waveguides, high-performance polarizers, and polarization-sensitive biosensors. We 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 our approach via three-dimensional numerical simulations. Finally, we illustrate the developed approach on the examples of nanowire-based high energy-density waveguides and non-magnetic negative index imaging systems with far-field resolution of one-sixth of vacuum wavelength.
