本文介绍了用矩量法评价介质随机分形表面散射电磁场的基本原理。给出了该算法的推导过程，并给出了可靠的分形轮廓生成程序。将数值结果与小扰动散射理论假设下的结果进行了比较和验证，并给出了现有文献的适用范围。讨论了与MoM相关的关键参数的选择。最后利用数值结果研究了分形表面的电磁散射行为。
This paper presents the rationale for the use of method of moments (MoM) for evaluation of electromagnetic field scattered by dielectric random fractal surfaces. Derivation of the algorithm is given along with a reliable fractal profile generation procedure. Numerical results are compared and validated against those obtained under the hypotheses of the small perturbation scattering theory, available together with the applicability limits in the current literature. Choice of key parameters pertinent to MoM is also discussed. Numerical results are finally used to investigate the behavior of the electromagnetic scattering from fractal surfaces.
