Abstract

Super-resolution properties of super-resolution near-field structures (super-RENS) are analyzed by a simplified Fourier optics approach. Statistical averages of near-field optical disks with random nanostructures are calculated to realize their general behaviors. Averaged readout waveforms of near-field optical disks with random apertures are calculated numerically. The resolution of a near-field optical disk is determined by the size and shape of the random nanostructure.
