Yuqing Cheng

摘要:

采用经典的谐振子模型研究了平面内任意构型的耦合金属纳米粒子的光学性质。耦合系数是从经典电动力学推导出来的。利用这个模型,我们可以很容易地得到耦合的MNP的光谱随系统的配置和外部光的偏振。进一步揭示了不同结构的远场电场分布。这个模型是我们以前只讨论平行和垂直激发的工作的推广。对相关应用有一定的参考价值

英文摘要:

A classic harmonic oscillator model is developed to investigate the optical properties of coupled metal nanoparticles (MNPs) with arbitrary configuration in plane. The coupling coefficients are derived from classical electrodynamics. Using this model, we can easily obtain the spectra of coupled MNPs varying with the configurations of the system and the polarizations of external light. Furthermore, the far field electric field distributions of different configurations are revealed. This model is an extension of our previous works which only discuss the parallel and vertical excitations for dimer. It is useful to related applications
