Organic-Inorganic Hybrids for Energy & Environmental Applications
07 Feb 2012 | Online Presentations | Contributor(s): Emmanuel P. Giannelis
In recent years, "storm clouds" have been forming at the interface of energy resources, environment, and climate change that demand concerted action by scientists, engineers, and policy makers. In this talk I will present a new materials platform based on organic-inorganic hybrids that provides …

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 …

Invisible cloaks and the perfect lens
16 May 2011 | Online Presentations | Contributor(s): John Pendry
Refractive materials gives us some limited control of light: we can fashion lenses, and construct waveguides, but complete control of light is beyond simple refracting materials. Ideally we might wish to channel and direct light as we please just as we might divert the flow of a fluid. Manipulation …

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 …
