本文研究了由金属长椭球和扁椭球纳米颗粒组成的集合体的光学性质。获得了平均吸收截面和散射截面、吸收系数、散射系数及反射系数的频率依赖关系。计算针对由不同金属构成的椭球形颗粒集合体进行。对于长椭球和扁椭球集合体，吸收截面和散射截面频率特性的计算结果差异体现在极大值的位置和数值上。确立了吸收系数和散射系数频率依赖关系的定性相似性。研究表明，不同金属椭球集合体的频率曲线在从可见光到紫外光谱范围内的极值位置存在显著差异。
英文摘要
The paper studies the optical properties of assemblies of metallic prolate and oblate nanospheroids. The frequency dependences of averaged absorption and scattering cross-sections, absorption, scattering and reflection coefficients are obtained. The calculations were performed for assemblies of spheroidal particles of various metals. The difference in the results of calculating the frequency characteristics of the absorption and scattering cross-sections for assemblies of prolate and oblate spheroids manifested itself in different location and value of the maxima. A qualitative similarity of the frequency dependences of the absorption and scattering coefficients was established. It is shown that the frequency curves of assemblies of spheroids of different metals differ significantly in the location of the extrema within the range from the visible to the ultraviolet region of the spectrum
