Plasmonic super-oscillations and sub-diffraction focusing
We demonstrate experimental focusing of surface plasmon polaritons beyond the plasmon diffraction limit using a super-oscillatory plasmonic antenna at the wavelength of 785nm, achieving a hot-spot as small as 300nm.
Solid-immersion super-oscillatory lens for heat assisted magnetic recording technology and nanoscale imaging
We demonstrate a solid-immersion super-oscillatory planar lens for super-resolution applications with a 102 nm full-width at half maximum focal spot in a low-loss immersion medium.
