| 摘 要： | 利用基于Rao-Wihon-Glisson(RWG)基函数和双线性（LL）基函数的矩量法求解了任意形状理想导体目标的电磁场积分方程.通过几个计算实例的比较表明，在相同或类似的计算量的情况下，LL基函数比RWG基函数更为完备地描述实际的电流分布，并具有更高的求解精度和更快的收敛特性；同时，仅需作很小的改动，就可以将基于RWG基函数的矩量法程序改写成基于LL基函数的矩量法程序. |

| Abstract: | The Rao-Wilton-Glisson (RWG) basis functions and Linear-Linear (LL) basis functions are employed to solve the electromagnetic field integral equations of the arbitrary shaped perfect conductive objects with the method of moment. Several numerical examples are presented and compared. The results demonstrate that the LL basis functions can provide a better representation of the actual current distribution and result in the significant improvement in the accuracy and a faster convergence of the moment method solution of the magnetic field integral equations. This can be achieved with only minor modifications in the existing codes based on the RWG basis functions. |
| Keywords: | electromagnetic field integral equation method of moment RWG basis functions linear-linear (LL) basis functions |
