In this short article we present a new fast finite‐difference timedomain (FDTD) method. Producing exactly the same solution to Maxwell's equations as Yee's classic FDTD method, the fast FDTD method offers up to a 50% reduction in the number of multiplications, which is a very important indicator of the computational complexity of an algorithm. Mathematical analysis and computer simulations are given in the article. © 1994 John Wiley & Sons, Inc.
