A straightforward, conceptually simple technique is presented for incorporating periodic boundary conditions into the FDTD method. The method is valid over a wide range of angles of incidence (for the scattering case) or angles of scan (for the antenna case). The method is verified through comparison with results calculated using a frequency‐domain, mode‐matching method. © 2005 Wiley Periodicals, Inc.
