3D and 2D Metamaterials at Infrared Optical Frequencies
24 Jun 2012 | Online Presentations | Contributor(s): Igal Brener, Mohammad Mayy, Amanda Harding
Metamaterials (MM) provide for new ways of manipulating light and achieving complex functionality due to the ability to control the spatial distribution of the permittivity and permeability. This full functionality usually requires complex 3D assemblies of subwavelength resonators that are very …

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 …

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 …

Learning with nanoHUB
01 Aug 2012 | Online Presentations | Contributor(s): Quincy Leon Williams
Interactive media is the most valuable tool for engaging the younger generations of students and future researchers. Since, few instructors have the skills required to incorporate such new technology into their existing curricula, we developed a short seminar designed to bridge the gap between …
