Although unconditionally stable (US), the accuracy of ADI‐FDTD is not so high as that of conventional FDTD. In this paper, a high‐order US‐FDTD based on the weighted finite‐difference method is presented. A strict analysis of stability shows that it is unconditionally stable. And, more importantly, its numerical‐dispersion performance is superior to that of ADI‐FDTD. © 2005 Wiley Periodicals, Inc.
