摘　　要：为提高矩量法求解积分方程的精度,基于Laguerre多项式提出一种新型的高阶基函数法,将其应用于2维导体的电磁散射问题的求解.将计算结果与低阶矩量法和解析解进行比较可知:此高阶矩量法在较低的剖分情况下,具有较高的计算精度,表明该方法具有有效性和精确性.将此新型的高阶基函数法应用于电大导体散射目标时,其计算结果仍具有较高的精度.In order to improve the accuracy of solving the IE （integral equation ） lay uae memou of moments （MOM） , a method of new high-order basis function was proposed by Laguerre polynomials, which was used to solve the problem of electromagnetic scattering of two-dimensional conductor. Compared wth the results and low-order MOM with analytical solution, high-order MOM had high calculation accuracy with low size of mesh grid. It showed the effectiveness and accuracy of this method. In the scattering problems of electrically larger conductor, the new high-order basis function method had higher calculation accuracy.
