FDTD modeling of a polarization near-field scanning optical microscope

摘要

Maxwell equations were numerically solved by the finite-difference time-domain method in order to confirm and understand the effectiveness of observing thin surface nanostructures using a polarization near-field scanning optical microscope (NSOM), which was first indicated in an experiment by Sakai et al. (2004 Nanotechnology 15, S362-S364). A method that requires small computational resources to reproduce polarization NSOMs has been developed.
