Over the past thirty years, the FDTD algorithm has been shown to be a remarkably robust and accurate tool for the analysis of problems in electromagnetics. Indeed, the FDTD algorithm, or one of its variant forms, has been successfully applied in a number of disciplines outside of ``traditional'' electromagnetics, including acoustics, optics, and biology. Many of these publications can be found in the on-line database, but were not mentioned here in the interest of brevity. Since the FDTD method has attracted attention from so many researchers, the number of FDTD-related publications is quite large and keeping track of this growing body of literature can be challenging. It is our hope that the on-line database we have compiled can facilitate the exploration and tracking of FDTD-related publications. Alternatively, for those interested in exploring a broad range of FDTD-related issues from a single source, Kunz and Luebbers [9] and Taflove [304] have written books that are devoted to the FDTD method. The FDTD method has also been discussed in other texts that are not solely devoted to the topic, e.g., [305].
