| 摘 要： | 利用ＬＯＶＥ场等效原理，实现了从近场到远场的变换，有助于时域有限差分法对电磁散射远场问题的解决，并在此基础上开发了建立在ＭＡＴＬＡＢ平台上的时域有限差分法软件系统，以方便对电磁散射远场问题进行研究。利用该系统解决了三个电磁散射实例中的远场问题，并将其计算结果与理论或其它计算方法所得的结果进行了比较，结果吻合较好。

| Abstract: | LOVE's Equivalence Theorem is presented to solve far field characteristics of electromagnetic scattering problems in finite difference time domain method. Correspondingly, a finite difference time domain method system based on MATLAB plane is developed by the authors. Some examples are studied by the system, and results are compared with ones calculated with other methods for validation. |
