Experimental Verification of a Negative Index of Refraction
- R. A. Shelby, D. Smith, S. Schultz
- Physics, Medicine
- Science
- 6 April 2001
We present experimental scattering data at microwave frequencies on a structured metamaterial that exhibits a frequency band where the effective index of refraction (n) is negative. The material… Expand
Determination of effective permittivity and permeability of metamaterials from reflection and transmission coefficients
- D. R. Smith, S. Schultz, P. Markoš, C. M. Soukoulis
- Physics
- 28 November 2001
We analyze the reflection and transmission coefficients calculated from transfer matrix simulations on finite lengths of electromagnetic metamaterials, to determine the effective permittivity ~«! and… Expand
Shape effects in plasmon resonance of individual colloidal silver nanoparticles
- J. Mock, M. Barbic, D. R. Smith, D. Schultz, S. Schultz
- Chemistry
- 2 April 2002
We present a systematic study of the effect of size and shape on the spectral response of individual silver nanoparticles. An experimental method has been developed that begins with the detection and… Expand
Single-target molecule detection with nonbleaching multicolor optical immunolabels.
- S. Schultz, D. R. Smith, J. Mock, D. Schultz
- Chemistry, Medicine
- Proceedings of the National Academy of Sciences…
- 1 February 2000
We introduce and demonstrate the use of colloidal silver plasmon-resonant particles (PRPs) as optical reporters in typical biological assays. PRPs are ultrabright, nanosized optical scatterers, which… Expand
Limitations on subdiffraction imaging with a negative refractive index slab
- D. Smith, D. Schurig, M. Rosenbluth, S. Schultz, S. Ramakrishna, J. Pendry
- Materials Science, Physics
- 28 June 2002
A planar slab of material, for which both the permittivity and permeability have the values of −1, can bring not only the propagating fields associated with a source to a focus, but can also refocus… Expand
The asymmetric lossy near-perfect lens
- S. Ramakrishna, J. Pendry, D. Schurig, D. Smith, S. Schultz
- Physics
- 28 June 2002
We extend the ideas of the perfect lens recently proposed [J.B. Pendry, Phys. Rev. Lett. 85, 3966 (2000)] to an alternative structure. We show that a slab of a medium with negative refractive index… Expand
Direct calculation of permeability and permittivity for a left-handed metamaterial
- D. Smith, D. Vier, N. Kroll, S. Schultz
- Physics
- 26 September 2000
Recently, an electromagnetic metamaterial was fabricated and demonstrated to exhibit a “left-handed” (LH) propagation band at microwave frequencies. A LH metamaterial is one characterized by material… Expand
Ab initio numerical simulation of left-handed metamaterials: Comparison of calculations and experiments
- T. Weiland, R. Schuhmann, +5 authors S. Schultz
- Physics
- 31 October 2001
Using numerical simulation techniques, the transmission and reflection coefficients, or S parameters, for left-handed metamaterials are calculated. Metamaterials consist of a lattice of conducting,… Expand
Left-Handed Metamaterials
- D. Smith, Willie J Padilla, +4 authors S. Schultz
- Physics
- 2001
The response of a material to electromagnetic radiation can be entirely characterized by the material parameters: the electrical permittivity, or e, and the magnetic permeability, or μ. The range of… Expand
Spectral response of plasmon resonant nanoparticles with a non-regular shape.
- J. Kottmann, O. Martin, D. Smith, S. Schultz
- Materials Science, Medicine
- Optics express
- 22 May 2000
We study the plasmon resonances of 10 (nm)--100 (nm) two-dimensional metal particles with a non-regular shape. Movies illustrate the spectral response of such particles in the optical range. Contrary… Expand
