摘　　要：提出了一种用于分析电磁问题的新型的数值方法,采用这种方法可以在降维了的空间里获得精度层次不同的解,从而大大地节省了分析电磁问题时的计算时间和内存要求。采用这个方法分析了几种线天线,并与用常规矩量法算出的结果或与相关文献给出的结果进行了比较,它们之间良好的一致性说明了本方法的正确性和有效性。A new numerical method of analyzing electromagnetic problems is presented in this paper, which allows a solution to electromagnetic problems to be found in different accuracy levels with error correction in each level determined in a dimensionreduced space. It therefore greatly reduces both the computation time and the storage requirement. Some wire antennas are analyzed by means of this method and the calculated results are compared with those obtained either by using a conventional method of moments or available in relevant published literatures.
