Is Graphene Alone in the Universe?
Online Presentations | 05 Dec 2012 | Contributor(s):: Jacob B. Khurgin
In this talk we show that many heterostructures based on III-V (InGaSb) and II-VI (HgCdTe) semiconductors can be engineered to have all the above properties nearly indistinguishable from those of graphene, while adding certain degree of versatility, such as ability to have not only 2-dimensional,...

Nanophotonics with Metamaterials
Online Presentations | 27 Aug 2012 | Contributor(s):: Vladimir M. Shalaev
One of the most unique properties of light is that it can package information into a signal of zero mass and propagate it at the ultimate speed. It is, however, a daunting challenge to bring photonic devices to the nanometer scale because of the fundamental diffraction limit. Metamaterials can...

3D and 2D Metamaterials at Infrared Optical Frequencies
Online Presentations | 24 Jun 2012 | 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...

Taming Light and Electrons with Metamaterials
Online Presentations | 11 Jul 2011 | 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...

Negative Refraction, Light Pressure and Attraction, Equation E=mc2 and Wave-particle Dualism
Online Presentations | 24 Feb 2011 | Contributor(s):: Victor G. Veselago
The process of transfer of radiation from the emitter to the receiver is considered. It is shown that the mass transferred by radiation is not always associated with portable energy by Einstein's relation E = mc ^ 2.

Photonic Metamaterials: From Linear to Nonlinear Optics
Online Presentations | 14 Dec 2010 | 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...

Developments in Metamaterials and Transformation Optics
Online Presentations | 29 Mar 2010 | 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 which...

Metamaterials with low loss and gain
Online Presentations | 28 Jan 2010 | Contributor(s):: Mikhail A. Noginov
Optical loss caused by absorption in metal and a need for active control are among the major challenges of plasmonic metamaterials. Both can be addressed by utilizing optical gain. Recent efforts aimed at the reduction of loss and the stimulated emission in nanoplasmonic systems with gain will be...
