| Abstract: | An unconditionally stable precise integration time‐domain method is extended to 3‐D circular cylindrical coordinates to solve Maxwell's equations. In contrast with the cylindrical finite‐difference time‐domain method, not only can it remove the stability condition restraint, but also make the numerical dispersion independent of the time‐step size. Numerical results are presented to demonstrate the effectiveness of this method. © 2008 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2009. |
