二维圆盘中不同外场对等离激元激发的影响
Effect of the Different External Fields on Plasmon Excitations in Two-Dimensional Disk
摘要: 基于自由电子气体模型和无规相近似下的线性响应理论，我们研究了二维圆盘中的等离激元。借助能量损耗谱和电荷分布，不同外场对等离激元模式的影响被获得。结果显示：均匀电场只能激发偶极等离激元，而非均匀电场既可激发偶极等离激元，也可激发四极等离激元。
Abstract: We study the plasmon excitations in two-dimensional disk, based on the linear response theory in the random-phase approximation and the free-electron gas model. With the help of energy absorption spectrum and charge distribution, the effect of external electric fields on plasmon is obtained. Results show that the uniform external electric field only can excite quadrupole plasmon; the non-uniform external electric field can excite both quadrupole plasmon and quadrupole plasmon.
