Journal ArticleDOI
Ultrafast spontaneous emission source using plasmonic nanoantennas.
Thang B. Hoang,Gleb M. Akselrod,Christos Argyropoulos,Jiani Huang,David R. Smith,Maiken H. Mikkelsen +5 more
TL;DR: The nanopatch antenna geometry can be tuned from the visible to the near infrared, providing a promising approach for nanophotonics based on ultrafast spontaneous emission and indicates a high radiative quantum efficiency of ∼50%.
Journal ArticleDOI
A full-parameter unidirectional metamaterial cloak for microwaves
TL;DR: This work design and experimentally characterize a two-dimensional, unidirectional cloak that makes no approximations to the underlying transformation optics formulation, yet is capable of reducing the scattering of an object ten wavelengths in size and regains the performance characteristics promised by transformation optics.
Journal ArticleDOI
Gradient index metamaterials.
TL;DR: The gradient index metamaterial proposed may be suited for terahertz applications, where the magnetic resonant response of SRRs has recently been demonstrated and may prove an advantageous alternative approach to the development of gradient index lenses and similar optics.
Journal ArticleDOI
Negative refractive index metamaterials
TL;DR: In this article, a negative refractive index property is found in metamaterials that exhibit exotic and unique electromagnetic properties not inherent in the individual constituent components. But, the negative index is not found in any known naturally occurring material.
Journal ArticleDOI
Limitations on Sub-Diffraction Imaging with a Negative Refractive Index Slab
David R. Smith,David Schurig,Marshall N. Rosenbluth,S. Schultz,S. Anantha Ramakrishna,John B. Pendry +5 more
TL;DR: In this article, the sensitivity of the subwavelength focus to various slab parameters, pointing out the connection to slab plasmon modes, is discussed, and a paradox associated with the perfect imaging of a point source is resolved.
