摘要
本文用场量迭代方法对三维电场积分方程进行数值求解,得到了给定电磁波照射下介质体内的场分布,并由此求得介质体外的散射场.从本文给出的几个算例看出,得到的解能较快收敛,并且避免了矩阵求逆运算,具有运算简便与速度快等优点。本文给出的薄板形介质的计算结果与现有文献的实验结果和计算结果进行了比较.证实了本文方法的正确性。
: The iteration technique is presented for solving three-dimensional vector integral equation. The field distribution in dielectric objects illuminated by a given wave is obtained, thus the scattering field outside a dielectric object is determined. The numerical results from the method are compared with the ones from other methods. The effectiveness and accuracy of the method are proved from the investigation, and the problem encountered in other methods are avoided.
