The simulated optical properties of silver nanodisks are presented. The extinction, absorption, and scattering efficiencies are calculated using the discrete dipole approximation. The influence of the nanodisk size, truncature (snip), aspect ratio, and environment on the plasmon resonance bands is investigated. In particular, the dipolar and multipolar resonance peak positions have been related to the specific features of the nanodisk geometry. An interpretation of the origins of each multipolar mode is proposed for the first time taking into account this geometry.
本文展示了银纳米盘的模拟光学特性。利用离散偶极近似法计算了消光、吸收和散射效率。研究了纳米盘尺寸、截断（剪裁）、纵横比和环境对等离激元共振带的影响。特别地，偶极和多极共振峰位置与纳米盘几何形状的特定特征相关。首次考虑这种几何形状，对每个多极模式的起源进行了解释。
