A finite-difference-time-domain (FDTD) method for the efficient solution of wideband electromagnetic phenomena is described. The algorithm uses a second-order Lax-Wendroff finite-difference algorithm in conjunction with the method of flux-corrected transport (FCT) to suppress problems with dispersion that occur when solving Maxwell's equations using the standard second-order Yee FDTD algorithm. Results comparing the accuracy of the Lax-Wendroff/FCT method and the Yee algorithm for propagating pulsed-type plane waves are given.
