Understanding secondary light emission by plasmonic nanostructures may improve medical imaging
Applications in imaging and sensing typically involve the emission of light at a different wavelength than the excitation, or "secondary light emission." The interpretation of resonant secondary light emission ...
Researchers lay out theory for metamaterials that act as an analog computer
The field of metamaterials has produced structures with unprecedented abilities, including flat lenses, invisibility cloaks and even optical "metatronic" devices that can manipulate light in the way electronic ...
