Simulation of super resolution near-field structure (super-RENS) using finite differential time domain (FDTD) method

In this paper, modified finite differential time domain (FDTD) method is used to investigate super resolution near-field structure (Super-RENS). The random distributed Ag particles, which is responsible for the localization and the enhancement of the surface plasmon within the Super-RENS, is included in this simulation. The near-field optical distribution when recording mark is just beneath the nonlinear aperture is achieved. And the transmitted readout signal is also simulated.
