| 摘 要： | 为研究超细颗粒物近场散射光强分布的特性,应用了时域有限差分方法系统对不同尺寸微小颗粒的近场散射光强进行分析。对于单颗粒的散射光场,颗粒越小,散射光主要表现为各向同性,随着颗粒增大,前向散射光将占主要部分,这与传统的Mie散射理论相一致。对于紧靠的两个颗粒,由于多重散射的作用,散射光场表现出更多的复杂性,两个颗粒的排列方式不同也会对结果有较大影响。这些结果为进一步分析复杂颗粒系统的光散射特性提供了基础。

| Abstract: | In order to study the near-field light scattering characteristics of superfine particles, the finite-difference time-domain systems were used to analyze the near-field light scattering characteristics about the superfine particles in different sizes. The light scattering analysis about single particle showed that the light reflected mainly in isotropic when the particles were small. With the size of particle enlarged , the former to the scattered light accounted for the major part, and these results met the... |
