The polarizability of an array of metallic spheres embedded in a dielectric host sphere is obtained by means of a quasi-static analysis of the electromagnetic interaction. The proposed model is validated through comparisons with the results obtained with software based on the finite element method. A parametric study of the polarizability as a function of the number of inclusions, their radii, and their positions is presented. An analysis of the plasmon resonances of the particle as a function of the same parameters is performed.
通过对电磁相互作用进行准静态分析，得到了嵌入电介质主体球中的金属球阵列的极化率。通过与基于有限元方法的软件所得到的结果进行比较，对所提出的模型进行了验证。给出了极化率随内含物数量、半径及其位置变化的参数研究。对粒子的等离子体共振随相同参数的变化进行了分析。
