摘　　要：文章应用最佳一致逼近理论构建了一种高阶基函数方法,并将其应用于二维电磁散射问题的求解。将计算结果与传统矩量法及解析解比较可知,该高阶矩量法在较低的剖分情况下,具有很高的计算精度。将此新型的高阶基函数方法用于电大导体和其它形状散射问题中,计算结果依然有较高的计算精度,从而有效降低了计算复杂度。A method of high-order basis function is constructed by the theory of the best uniform approximation, which is used to solve the two-dimensional electromagnetic scattering problem. Numerical results are compared with those by the conventional method of moments（MOM）and analytical solutions. It is shown that the high-order MOM has higher computational precision with lower discretization. The new high-order basis function is applied to the scattering problems of electrically large conductors and other shaped objects. Numerical results prove that the proposed method possesses high accuracy and can reduce computational complexity efficiently.
