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.
