Paper Abstract

In this paper, three types of simulations will be performed using the three-dimensional finite difference time domain (3D-FDTD) method. First, we simulate the visualized interaction procedure of evanescent field coupling to the PSTM probe tip. Then, we show the variation in the field distribution above the sample as its refractive index and thickness are increased. Finally, we simulate the refractive index images based on the principle of separation of the refractive index image from the images of AF/PSTM for the realistic experiments. The numerical results are in good coincidence with the experimental results.
