Monte Carlo simulation of random rough surface is carried out using the finite‐difference time‐domain (FDTD) method. The solution domain is truncated using a periodic and an absorbing boundary condition. The advantages of using FDTD include (1) matrix inversion is eliminated, (2) time‐domain response is readily available, and (3) scattering intensities for a range of frequencies can be obtained simultaneously.
