摘要

提出了一种计算金属纳米粒子在光学波段的三维电磁波散射的数学收敛方法。该方法基于求解Muller边界积分方程组。导出了光学定理的组成部分:总散射截面(TSCS)和消光截面(ECS)的计算公式。给出了平面电磁波在具有两种不同形状和电尺寸的纳米粒子上的不同入射角和极化情况下这些特性的计算示例结果。这些结果证明了在某些波长表面等离子体(SP)模式上的共振。

3-D Electromagnetic Scattering by Ellipsoidal Silver Nanoparticles in Optical Band

Presented is a mathematically convergent method of calculation of 3-D electromagnetic wave scattering by metal nanoparticles in the optical wavelength band. The method is based on solving the set of the Muller boundary integral equations (IEs). The formulas are derived for the components of optical theorem: total scattering cross-section (TSCS) and extinction cross-section (ECS). Sample results of calculation of these characteristics are shown for various angles of incidence and polarization of a plane electromagnetic wave on a nanoparticle having two different shapes and electric sizes. These results demonstrate the resonances on the surface-plasmon (SP) modes at certain wavelengths.
