Paper Abstract

It is important to analyze the images obtained by photon scanning tunneling microscope (PSTM). Recently some theories have been developed including finite-difference time-domain (FDTD) method applied in near field optics. In this article wc extend a simple FDTD method (equivalent incident wave method) to PSTM system, which has been widely used to detect objects buried underground in geophysics. In PSTM system lighting wave is evanescent wave, that is the equivalent incident wave exciting the samples and probe over the interface. Numerical simulations show that the results ofthis method are in agreement with the results ofthe moment method and perturbation theory.
