Trends in Nanoplasmonics: Smaller, Stronger, Faster!
25 Apr 2011 | Online Presentations | Contributor(s): Mark I Stockman
Nanoplasmonics deals with collective electron dynamics on the surface of metal nanostructures, which arises due to excitations called surface plasmons. The surface plasmons localize and concentrate optical energy in nanoscopic regions creating highly enhanced local optical fields. They undergo …

Developments in Metamaterials and Transformation Optics
29 Mar 2010 | Online Presentations | Contributor(s): David R. Smith
Metamaterials—artificially structured microcircuits that can mimic the electromagnetic response of atoms and molecules—have vastly expanded the opportunities available for the design of electromagnetic structures. Starting in 2000 with the first report of a “left-handed” metamaterial, for …

Taming Light and Electrons with Metamaterials
11 Jul 2011 | Online Presentations | Contributor(s): Nader Engheta
In recent years, in my group we have been working on various aspects of metamaterials and plasmonic nano-optics. We have introduced and been developing the concept of "metatronics", i.e. metamaterial-inspired optical nanocircuitry, in which the three fields of "electronics", "photonics" and …

Enhancing the Light-Matter Interaction with Optical Antennas
02 Jun 2011 | Online Presentations | Contributor(s): Lukas Novotny
Optical antennas are devices designed to efficiently convert optical radiation into localized energy, and vice versa. They enhance the interaction between light and matter, and have the potential to boost the efficiency of optoelectronic devices ranging from light-emitting diodes to solar cells. In …

Photonic Metamaterials: From Linear to Nonlinear Optics
14 Dec 2010 | Online Presentations | Contributor(s): Natalia Litchinitser
Metamaterials open unparalleled opportunities for "engineering" previously inaccessible values of refractive indices from positive to near-zero and even negative values, and new avenues for light manipulation. While an enormous progress has been made in the field of linear optics of uniform …
