This work addresses the need for a fully-retarded theoretical model for surface plasmons on metal nanoparticle chains and arrays embedded in a multilayered medium. The proposed method uses dyadic layered medium Green's functions not only to obtain the electric field created by an oscillating electric dipole but also to modify the polarizability of nanoparticles in a multilayered medium appropriately. Theoretically calculated resonance frequencies show a very good agreement with the experimental results found in the literature. Theoretical results suggest that surface plasmon propagation lengths of 1 micrometer are possible using silver or gold nanoparticles embedded in a multilayered medium.
这项工作满足了对嵌入多层介质中的金属纳米颗粒链和阵列上表面等离子体激元的全延迟理论模型的需求。所提出的方法不仅使用并矢分层介质格林函数来获得由振荡电偶极子产生的电场，还能适当地修正多层介质中纳米颗粒的极化率。理论计算的共振频率与文献中的实验结果非常吻合。理论结果表明，使用嵌入多层介质中的银或金纳米颗粒，表面等离子体激元的传播长度可达1微米。
