Controlling Electromagnetic Fields
- J. Pendry, D. Schurig, D. Smith
- Physics, Medicine
- Science
- 23 June 2006
Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields—electric displacement field D,… Expand
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
Metamaterial Electromagnetic Cloak at Microwave Frequencies

- 10 November 2006
A recently published theory has suggested that a cloak of invisibility is in principle possible, at least over a narrow frequency band. We describe here the first practical realization of such a… Expand
Electromagnetic parameter retrieval from inhomogeneous metamaterials.
- D. Smith, D. Vier, T. Koschny, C. Soukoulis

- 22 March 2005
We discuss the validity of standard retrieval methods that assign bulk electromagnetic properties, such as the electric permittivity epsilon and the magnetic permeability mu, from calculations of the… Expand
An Overview of the Theory and Applications of Metasurfaces: The Two-Dimensional Equivalents of Metamaterials
- C. L. Holloway, E. F. Kuester, J. Gordon, J. O'Hara, J. Booth, D. Smith

- IEEE Antennas and Propagation Magazine
- 3 July 2012
Metamaterials are typically engineered by arranging a set of small scatterers or apertures in a regular array throughout a region of space, thus obtaining some desirable bulk electromagnetic… Expand
Full-wave simulations of electromagnetic cloaking structures.

- 26 July 2006
Pendry et al. have reported electromagnetically anisotropic and inhomogeneous shells that, in theory, completely shield an interior structure of arbitrary size from electromagnetic fields without… Expand
Calculation of material properties and ray tracing in transformation media.

- 24 July 2006
Complex and interesting electromagnetic behavior can be found in spaces with non-flat topology. When considering the properties of an electromagnetic medium under an arbitrary coordinate… Expand
Design of electromagnetic cloaks and concentrators using form-invariant coordinate transformations of Maxwell’s equations
- M. Rahm, D. Schurig, D. A. Roberts, S. Cummer, D. Smith, J. Pendry
- Physics

The technique of applying form-invariant, spatial coordinate transformations of Maxwell’s equations can facilitate the design of structures with unique electromagnetic or optical functionality. Here,… Expand
Probing the mechanisms of large Purcell enhancement in plasmonic nanoantennas
- G. M. Akselrod, C. Argyropoulos, +5 authors M. H. Mikkelsen

- 1 November 2014
Plasmonic nanostructures enable spontaneous emission enhancement factors of greater than 1,000 — the largest observed to date. The orientation of dipole emitters in nanogaps plays a vital role.
Broadband Ground-Plane Cloak
The possibility of cloaking an object from detection by electromagnetic waves has recently become a topic of considerable interest. The design of a cloak uses transformation optics, in which a… Expand
