| Abstract: | Transformation from near zone to far zone is discussed, especially in the time domain. The feasibility is proved theoretically at first. Then the transformation procedures are given in detail.To show the validity an example is given. The method discussed here provides convenience to the application of FDTD in the wide band problems, and extends the application area of FDTD. |
