垂直入射时无限长多层介质圆柱的内、外场计算

Internal and External Electromagnetic Fields for Multilayered Cylinder at Normal Incidence

本文提出了一种稳定而准确的迭代算法，计算任意多层吸收介质圆柱电磁散射的散射系数ａｎⅡ和ｂｎⅠ及各层内场系数，给出了它们适合于计算机数值计算的形式和数值结果，该算法对于各种复介电常数和复磁导率以及电尺寸参数均适用。

A more stable and accurate recursing formula and computing procedure to calculate the scattering coefficients anⅡ,bnⅠ and the internal coefficients cn(j),dn(j),gn(j),fn(j) are proposed. The numerical calculations and tests based upon the recursive algorithms are presented. This procedure can be used to inhomogeneous cylinders with any complex refractive indices and size parameters.
