| 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.

| Abstract: | In order to improve the accuracy of solving the IE(integral equation) by the method 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. |
