Abstract

We present three-dimensional simulations ofthe image formation of periodic structure in near-field optical microscopy with the three-dimensional finite-difference time-domain method (FDTD). Our calculations consider three cases for samples with different periods a with respect to the propagation wavelength X: (1) ?>?; (2) ?=?; (3) ??, the image ofthe sample can be obtained in the Talbot plane; while ?=? or ?
