研究了一种求解阵列单元表面电流的新方法,该方法利用了RWG基函数的特殊性质,在阵列电流为矢量的情况下,通过将阵列单元进行三角形剖分而有效的计算了电流分布。分别讨论了RWG基函数的性质及其在计算电场积分方程和阵列表面电流推导中的应用,并给出了具体的仿真结果。此方法在计算不同形状阵列单元表面电流具有极高的准确性和有效性。与以往的矩量法相比,该方法具有计算准确,物理意义明确等特点,可以应用于弹体上天线阵元电流的计算。

A new method is introduced that can he used in the solution of surface current distribution'over array cell.Be- cause the array current is a vector,it is possible to divide it into small triangulars.Through the analysis of RWG function and the electric field interal equation,and through the simulation,it is proved that this method can obtain exact suiace current over several different array cell.effectively.Compared with other means,this method can be used in bomb be- cause it has many virtues such as exact result and explicit physical signification.
