Abstract:

本文提供了在矩形原子团簇中查找等离激元的新方法。利用此方法可以克服目前在寻找等离激元模式时，结果易受外场影响的缺点。此外，本文还提供了等离激元的本征电荷分布。通过分析本征电荷分布，可以为等离激元的激发方案提供启示。
In this paper, we present a new method to find the plasmon in two dimensional rectangular atomic clusters. Using this method, we can overcome the disadvantage that the results are easily affected by the external field when we are looking for plasmon modes. In addition, the eigen-charge distributions of the plasmon is also provided, which can provide inspiration for plasmons excitation.
