摘　　要：推导了平行导线任意阵列电磁散射边值问题的高阶解,利用矩量法给出了 该问题离散空间对应的线性代数方程组。通过数值仿真和互易定理检验了该方法的 有效性,同时表明考虑高阶解在平行导线任意阵列雷达散射截面高精度预估中的必 要性。The boundary value problems corresponding to the higher-order solutions to electromagnetic scattering by an arbitrary array of parallel perfect conducting wires are first formulated in order to investigate numerically in later part the correctness and validity, which is proceeded by the corresponding linear algebraic equations spanned in the discrete space with the use of method of moments (MoM). Reciprocity theorem is also utilized as a standard to verify the effectiveness of the method developed, thus indicating the necessity of higher-order solutions in predicting the radar cross section (RCS) of the geometry under consideration with high precision.
