Understanding the Finite-Difference Time-Domain Method
eecs.wsu.eduon the finite-difference time-domain (FDTD) method. The FDTD method makes approximations that force the solutions to be approximate, i.e., the method is inherently approximate. The results obtained from the FDTD method would be approximate even if we used computers that offered infinite numeric precision.
