Numerical modeling of spectroscopic response, and near-field effects including local field enhancement and local optical chirality induced by metallic non-chiral nanostructures under continuous-wave laser excitations are presented in this paper. Particularly, excited-state dynamics including plasmon resonances and local optical activity is studied. The light-matter interaction problem is described through Maxwell's equations which are numerically solved by the boundary element method. The calculations are verified by the corresponding experiments. Knowledge of excited-state dynamics of metallic nanostructures provides valuable guidelines for designing alternative functional nanomaterials that is benefited from the enhanced light-matter interaction.

金属纳米结构附近的激发态动力学电磁模型

本文介绍了光谱响应的数值模型,以及在连续波激光激发下由金属非手性纳米结构引起的近场效应,包括局部场增强和局部光学手性。特别地,研究了包括等离子体共振和局部光学活性的激发态动力学。通过麦克斯韦方程描述光-物质相互作用问题,该方程通过边界元方法进行数值求解。通过相应的实验验证了计算结果。金属纳米结构的激发态动力学知识为设计替代功能性纳米材料提供了有价值的指导,而这种功能性纳米材料得益于增强的光-质相互作用。
