Abstract

In this paper, a non - color far - field ultra - focused surface plasma exciton nanostructure is proposed. The structure is composed of multiple rings and multiple grooves. The super oscillation effect of radial polarized light irradiation in concentric multi-annulus is produced. Multiple grooves scatter surface plasma polarons (SPPS) into free space at the nanoscale. The interaction between the nanometer superfocusing effect and the super oscillation effect can form different focal points between the near field and the far field. Finite-difference time-domain (FDTD) method was used to numerically calculate the focal length (FL), full width at half maximum (FWHM) and depth of focus (DOF). Achromatic nanoscale superfocus from near field to far field provides an application method for dynamic 3D imaging and multilayer optical storage in super-resolution display.
