| 摘 要： | 利用体积分方程矩量法(MoM)及其多层快速多级子算法(MLFMA)研究了各向异性的电介质体或/和磁介质体目标的电磁散射问题,将多层快速多级子算法的计算结果与解析方法(Mie)或矩量法结果进行了对比分析.不但验证了MLFMA算法的高效性和精确性,同时该算法还适合于分析模拟任意复杂介质体(如各向异性磁化等离子体)目标的电磁散射问题,为进一步实现电大尺寸的任意复杂各向异性介质体/金属组合目标电磁散射分析的精确高效算法奠定了基础.

| Abstract: | The electromagnetic scattering from the anisotropic media with arbitrary permittivity and permeability tensors is studied here with the method of moments(MoM) and multilevel fast multiple algorithm(MLFMA) of the volume integral equations(VIE).Numerical results are presented and compared against the analytical solutions or results of the method of moments to demonstrate the accuracy and efficiency of the proposed Algorithm,and this algorithm can be extended to the analysis and simulation of arbitrary electromagnetic scattering from the complex media(e.g.anisotropic magnetized plasma) objects of perfectly electric conductor and has laid a foundation for the realization of accurate and efficient algorithm for the electromagnetic scattering analysis of arbitrary complex anisotropic media/metallic composition object of any size. |
