基于广义Mie理论求解方法(GMM),考虑单元粒子之间的相互作用,计算了不同尺度参数不同间距的双球聚集粒子的衰减因子、散射因子等辐射特性参数,同时分析了双球聚集粒子与不考虑相互作用计算所得的辐射特性差异,分析结果表明:考虑相互作用与不考虑相互作用计算所得的双球聚集粒子的辐射特性存在着一定的差别,这种差别随粒子间距、尺度参数的变化而变化,最大偏差达30%左右。
Based on the Generalized Multi-particle Mie-solution (GMM) method, the radiative properties of two-sphere clusters, such as the extinction efficiency factor, scattering efficiency factor, are calculated with different size parameter and different distance between the elemental spheres. Compared with the radiative properties of the spheres calculated by Mie theory (without considering the interactions among the particles), the results show that there exists many discrepancies, which change with the distance between the particles and size parameter, when considering the interactions among the particles. The maximum relative error is about 30%.
