The finite-difference time-domain (FDTD) method is employed to solve thethree dimensional Maxwell equation for the situation of near-field microscopyusing a sub-wavelength aperture. Experimental result on unexpected high spatialresolution is reproduced by our computer simulation.Comment: 2 pages, 3 figure
