Abstract

We investigate a hyperlens at l=1200 nm based on two fans of metal tips converging to a central zone where multiple nanoparticles have to be detected. The rich Green function of the system provides deep-subwavelength resolution, but sensitivity requires a novel dark-field scheme that we will detail, based on amplitude and phase control of the fields on the illumination fan.
