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

abstract

  • 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 ∼10  nm spot with an intensity enhancement ∼10(5) when the incident light is radially polarized.
