Study of local photomodification of nanomaterials using near-field optics
W. D. Bragg,Katyayani Seal,Viktor A. Podolskiy,V. P. Safonov,J. G. Zhu,Vladimir M. Shalaev,Z. Charles Ying +6 more
TL;DR: In this article, thin films of randomly distributed silver nanoparticles are studied experimentally using photon scanning tunneling microscopy and theoretically using real-space renormalization group method, revealing large variations of local optical intensity at sub-wavelength scales.
Journal ArticleDOI
Nanowire metamaterials with extreme optical anisotropy
TL;DR: In this article, an analytical description of electromagnetism in anisotropic nanowire-based metamaterials for negative-refraction waveguides, high-performance polarizers, and polarization-sensitive biosensors is presented.
Proceedings ArticleDOI
Broadband, low-dispersion, mid-infrared metamaterials

TL;DR: In this article, the authors show that using multiple-metamaterial semiconductor stacks of varying thickness and doping improves the performance of a single-stack mid-infrared metamaterial.
Journal ArticleDOI
Asymmetric reflectance and cluster size effects in silver percolation films
TL;DR: In this paper, a scaling-theory based technique reproduces the spectral properties of semicontinuous composites, as well as provides insight into the origin of experimentally observed loss, reflectance, and transmittance anomalies in the vicinity of the percolation threshold.

Abstract: We present an optical sensor based on plasmonic nanorod metamaterials. The sensor operates similar to well-established surface plasmon polariton sensors, but offers order-of-magnitude improvement over existing technology. Optical and biological applications are discussed.
