Size Effects of Localized Surface Plasmon Induced by Embedded Silver Nanoparticles in Near-field Optical Disk
In this paper,we report the near-field and far-field properties of AgOx-type super-resolution near-field structure with embedded silver nanoparticles of different sizes using two-dimensional finite-difference timedomain calculations. Highly localized enhancements were found near the surface of nanoparticles, and the near-field enhancements increased with the size of nano particles. The far-field difference signals of silver nano scatters confirm the super-resolution capability, and the difference signals were stronger for larger nanoparticles. The behaviors of far-field signals indicate the correlation between the enhanced localized surface plasmons and the super-resolution capabilities.
