利用金属纳米团簇实现电磁场的优化控制

Optimal control of electromagnetic field using metallic nanoclusters

Ilya Grigorenko, Stephan Haas, Alexander Balatsky, A. F. J. Levi

摘要:

利用非局域线性响应理论研究了金属纳米团簇在外加电磁场作用下的介电性质。在量子极限,我们发现一个非平凡的依赖感生场和电荷分布的集群之间的空间分离和驱动场的频率。使用遗传算法,这些量子功能被利用来定制设计具有频率控制切换能力的亚波长透镜。

英文摘要:

The dielectric properties of metallic nanoclusters in the presence of an applied electromagnetic field are investigated using non-local linear response theory. In the quantum limit we find a non-trivial dependence of the induced field and charge distribution on the spatial separation between the clusters and on the frequency of the driving field. Using a genetic algorithm, these quantum functionalities are exploited to custom-design sub-wavelength lenses with a frequency controlled switching capability.
