摘　　要：对 FDTD中近区场向远区场的转换方法作了讨论 ,具体分析了时域的转换方法 ,在理论上说明了该方法的可行性 ,给出了具体的转换步骤 ,并用典型的计算实例验证其正确性。该方法为 FDTD在宽频领域的应用提供了方便 。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.
