Finite-difference time-domain (FDTD) and finite-element time-domain (FETD) algorithms are among the most popular methods for the simulation of electromagnetics fields in the time-domain. This popularity stems in part from their unparalleled versatility and computational efficiency. The objective of this book is to present and study several state-of-the-art approaches aimed at improving the accuracy of FDTD and FETD for problems involving large-scale and/or disparate-size geometries. Topics discussed here include pre-asymptotic techniques to reduce numerical dispersion error, stable hybrid FDTD/FETD schemes using composite meshes, and stable perfectly matched layer implementations. This book should be of interest to researchers and practitioners involved in the development and application of FDTD or FETD to the growing number of technological areas that rely on electromagnetic simulations.
