Transmission of images with subwavelength resolution to distances of several wavelengths in microwave, terahertz and infrared ranges
Online Presentations | 08 Apr 2008 | Contributor(s):: Pavel Belov
The resolution of conventional imaging systems is restricted by thediffraction limit: the details smaller than half-wavelength of radiationcannot be resolved. Using novel engineered media with extreme opticalanisotropy and their waveguiding properties it is possible to overcomethe classical limit...

Plasmonic Metamaterials: Unusual Optics and Applications
Online Presentations | 28 Feb 2008 | Contributor(s):: Igor Smolyaninov
Surface plasmon-polaritons (or plasmons) are collective excitations of the conduction electrons and the electromagnetic field on the surface of such good metals as gold and silver. Near the frequency of surface plasmon resonance plasmons may perceive regular dielectrics as negative index...

Some Remarks to Electrodynamics of Materials with Negative Refraction
Online Presentations | 26 Jun 2007 | Contributor(s):: Victor G. Veselago
The negative refraction coefficient n < 0 can be introduced for isotropic materials with anti-parallel directions of phase and group velocities. If some of material can be described by negative n it will have also negative values of both (electrical ε and magnetic μ) permeabilities. In materials...

Plasmonic Nanophotonics: Coupling Light to Nanostructure via Plasmons
Online Presentations | 03 Oct 2005 | Contributor(s):: Vladimir M. Shalaev
The photon is the ultimate unit of information because it packages data in a signal of zero mass and has unmatched speed. The power of light is driving the photonicrevolution, and information technologies, which were formerly entirely electronic, are increasingly enlisting light to communicate...
