Plasmonic lens
The Plasmonic Lens is intended to manipulate and focus stimulated surface plasmon polaritons (SPP), resulting in a focus beyond the limitations of conventional lenses. This limitation is known as the diffraction limit and the experimental plasmonic lens is intended to produce image details that are not possible with conventional lenses, below the diffraction limit. These image details are intended to be available at wavelengths smaller than the wavelength of visible light. Another name for this result is "subwavelength imaging". Hence, the physical resolution limit can be overcome with this method. SPPs have been extensively studied, and are produced when light interacts with evanescent waves in the near field at the interface of conjoined metal and dielectric materials. Its intended uses are focusing, imaging, light beam shaping, subwavelength optics, subwavelength light wave guiding, novel optical and magneto-optic data storage, light generation, microscopy, biophotonics, biological molecule sensors, and solar cells, as well as other applications.
