A simple alternative way to position dielectric materials in the finite‐difference time‐domain (FDTD) Yee cell grid is proposed. Plane‐wave illuminated spheres are used as examples to study the performance of the alternative method compared to the standard FDTD method. Although the performances are generally equally good, the alternative method may sometimes give significantly improved accuracy. © 2008 Wiley Periodicals, Inc.
