Paper Abstract

In this study, we investigated light transmission based on a metallic nano-lens for imaging applications. The nano-lens consists of multiple nano-rings formed in a thin metal film. Four types of nano-lens structures in a 50-nm thick gold film were simulated using rigorous coupled-wave analysis. Each nano-lens is designed to operate as a lens element that focuses transmitted light. The results show the focal power increasing with the ring number and the enhancement of achievable numerical aperture compared to that of conventional lenses.
