Furthermore, several Finite-Difference Time-Domain (FDTD) codes have been written. These codes which include 2-D and 3-D cavity problems are an exploratory prelude to an FDTD near-field scanning optical microscope (NSOM) model. One specific concern for the NSOM model involves absorbing boundary conditions (ABCs). Specifically, ABCs are important for an NSOM model due to FDTD grid termination concerns. That is, the non-real reflected fields off of the FDTD grid edges must be minimized by some ABC. To this end, a MUR ABC was studied in a 2-D parallel-plate waveguide. Figure 1 below shows a gaussian pulse introduced in the grid and it's first reflection off the ABC. In order to emphasize the existence of the reflected pulse, the figure's inset shows a zoomed in view of the reflected pulse. At this point, work is just beginning on the actual FDTD NSOM model. With luck, some results from this new code will be posted soon.
