Abstract

The super resolution near field structure (SR) which incorporates an AgO_x thin film was studied using a finite difference time domain modeling tool. The goal is to explain the physical mechanism(s) responsible for the SR phenomenon in these types of structures. Both absorption and readout characteristics were studied. Modeling results indicate that the SR structure which contains a AgO_x active layer can produce super-resolution when the aperture formed in the active layer consists of a annular cylinder of small Ag particles which surround a transparent homogeneous `hole' filled with a low index material such as O₂.
