Journal ArticleDOI
Plasmon Ruler with Angstrom Length Resolution
Ryan T. Hill,Jack J. Mock,Angus Hucknall,Scott D. Wolter,Nan Marie Jokerst,David R. Smith,Ashutosh Chilkoti +6 more
TL;DR: It is found that the film-NP plasmon nanoruler is extremely sensitive at very short film- NP separation distances, yielding spectral shifts as large as 5 nm for every 1 Å change in separation distance.
Journal ArticleDOI
Origin of second-harmonic generation enhancement in optical split-ring resonators
TL;DR: In this article, the second-order nonlinear optical properties of metal-based metamaterials were investigated using a hydrodynamic model for electronic response, in which nonlinear surface contributions were expressed in terms of the bulk polarization.
Journal ArticleDOI
The asymmetric lossy near-perfect lens
TL;DR: In this article, a slab of a medium with negative refractive index bounded by media of different positive refractive indices was shown to act as a near-perfect lens for evanescent waves.
Journal ArticleDOI
Computational imaging using a mode-mixing cavity at microwave frequencies
Thomas Fromenteze,Okan Yurduseven,Mohammadreza F. Imani,Jonah N. Gollub,Cyril Decroze,David Carsenat,David R. Smith +6 more
TL;DR: In this paper, the authors presented a 3D computational imaging system based on a mode-mixing cavity at microwave frequencies, which encoded the scene information onto a set of frequency modes.
Journal ArticleDOI
Molecular and pathologic insights from latent HIV-1 infection in the human brain
Paula Desplats,Wilmar Dumaop,David R. Smith,Anthony Adame,Ian P. Everall,Scott Letendre,Ronald J. Ellis,Mariana Cherner,Igor Grant,Eliezer Masliah +9 more
TL;DR: Persistence of latent HIV-1 infection in the CNS was associated with increased levels of chromatin modifiers, including BCL11B, leading to inflammation, neurodegeneration, and neurocognitive impairment.
