摘要
对非金属体电磁散射中的积分方程,该文用正则摄动理论导出了它的渐近解,该解由参数η_s跟一组不依赖η_s的迭代方程组的解来构成,从而提高了数值解在研究参数η_s对目标特性影响时的效率.同时使用了外推法来加速渐近解的收敛,最后的结果跟同直接反演求解的结果吻合得相当好。
From the points of the regular perturbation theory,a kind of asymptotic solution is resulted from the integral equation applied in the electromagnetic scattering of non—metallic scatterer in this paper. The solution is constituted of both paraneter η and a series of iterative solutions which are free of parameten η. By means of it ,the efficiency of study of how parameter η, affects the object character for the numerical solution of integral equation emploged. In oredr to improve the convergent of asymptotic solution,extrapolation method is introduced to accelerating it the final result is compared with the one directly resutted from the equation,and excelleut agreement is demonstrated.
