| 摘 要： | 从理论上分析了利用时间有限差分法由近场到近场或远场转换的频域和时域两种方法，并选择时域的方法计算在FDTD计算范围内一给定点的电场值，与直接利用FDTD法得到的结果相比较，两者非常一致；最后利用该方法计算了功率变换器FDTD计算范围外一给定点的电磁场时间响应．

| Abstract: | Two techniques for transforming the near-field to near/far-field, in time-domain and in frequency-domain, are theoretically analyzed. The Kirchhoff Surface Integral Representation (KSIR) method is chosen and used. The results obtained by the KSIR method are good agreement with the data obtained by the direct FDTD method within the FDTD computational domain;and the electromagnetic fields varying with time at an observation point outside FDTD domain are calculated too. |
