Abstract

In this paper, the surface plasmon resonance (SPR) effects between solid silver (Ag) and Ag-shell nanoparticles (MNPs) in active layer of AgO_x-type super-resolution near-field structure (super-RENS) are numerically investigated and quantitatively compared by means of finite-difference time-domain method. Eight types of MNPs patterns, i.e., structure #1-#8 in active layer of super-RENS are studied. Results show that the proposed structure #3 and #7 in active layer shows higher field intensity than other structures corresponding to their SPR wavelengths. It is found that the structure #7 (square Ag-shell of MNPs) is the best choice in the view point of designing the AgO_x-type super-RENS. This study provides the information to design a super-RENS with superior resolution as well as other applications in nanophotonic devices.
