摘要
本文将只能分析两种电介质的广义多重散射理论推广到(n+1)种电磁混合介质的情况,并在此基础上导出了椭球状粒子的混合随机媒质的等效电磁参数ε_(ell)和ε_(ell)的计算公式,在一定程度上解决了含有金属粒子等强散射场的混合随机媒质问题。讨论了本文理论与其他理论的关系。理论计算值与实际测量数据吻合较好。
With the aid of a generalized mutiple scattering theory,the formula for effective electromagnetic parameters εeff and μeff of mixtulre media of random ellipsoid particles are derived and those formula have been applied to the strong scattering of metal particles for the first time.In the meantime the previous formula for only two kinds of dielectric media have been generalized to the (n+1) kinds of electric and magnetic media.The relation of out theory to other theories is also discussed,and theoretical results are in good agreement with the measured data.
