Nanoscale high-intensity light focusing with pure dielectric nonspherical scatterer. Academic Article uri icon


  • Light scattering from nonspherically symmetric pure dielectric structures is examined. From the finite element full-wave analysis, it is found that teardrop-shaped scatterers can focus visible light to a 10nm spot with an intensity enhancement 10(5) when the incident light is radially polarized.
