An efficient subcell scheme for modeling a thin perfectly conducting (PEC) sheet in the context of the finite‐difference time‐domain (FDTD) method is presented in this paper. The present approach removes the limitation, typically imposed in the conventional FDTD scheme, that the grid size be commensurate with the dimension of the object being modeled. The proposed approach is easy to implement, is numerically stable, and yields results that are found to be accurate compared to the ones derived by using the conventional FDTD scheme. © 2001 John Wiley & Sons, Inc.
