    02 Aug 2007 | | Contributor(s):: Karina Moore

    Light can be used to excite plasmon resonance in gold nanoparticles. Plasmon resonance occurs on the nanoscale as the particles become excited and plasmon oscillations arise in each particle of a pair of metal nanoparticles. There is plasmon coupling between the neighboring particles as the...

  5. BNC Annual Research Review: Transforming Light with Metamaterials

    02 Dec 2009 | | 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...
