Spatial Resolution of Near-Field Scanning Optical Microscopy with Sub-wavelength Aperture
arXiv:physics/9911001 · doi:10.1143/PTPS.138.173
Abstract
The finite-difference time-domain (FDTD) method is employed to solve the three dimensional Maxwell equation for the situation of near-field microscopy using a sub-wavelength aperture. Experimental result on unexpected high spatial resolution is reproduced by our computer simulation.
