有源随机球粒媒质的非弹性多散射

依据有源分子的等效偶极子模型,本文首先用并矢格林函数方法给出了含有有源分子的单球粒的非弹性散射分析。然后,以建立的随机球状颗粒媒质的弹性多散射理论为基础,导出了含有有源分子的随机球粒媒质的非弹性多散射理论,给出了非弹性多散射场在整个空间的矢量球波函数展开,展开系数可由一组耦合线性方程解得。

INELASTIC MULTIPLE SCATTERING BY ACTIVE RANDOMLY DISTRBUTED SPHERICAL SCATTERERS

According to the model of equivalent dipoles for active molecules, the analysis of inelastic EM scattering by active molecules embedded in a sphere is given by the method of dyadic Green's functions at first, and rhen, based on the theory of elastic muptiple scattering by randomly distributed spherical scatterers, a new theory for analysis of inelastic multiple scattering by active molecules embedded in randomly distributed spherical scatterers is developed. This theory gives the expansions of the multiple scattering fields in all space region in terms of vector spherical wave functions in which the expansion coefficients can be solved from a ses of coupled linear equations.
