FDTD模拟金海胆结构的局域等离子体共振

FDTD Simulation of the Gold Urchin-like Nanoparticles for the Localized Surface Plasmon Resonance

利用了Finite-Difference Time-Domain方法,对金海胆结构的局域等离子体共振进行了研究。分别考虑了空心和刺的尺寸,刺的分布及介电环境因素对共振峰的贡献。结果将使人们更深入地理解级次纳米结构与局域表面等离子体共振之间相互关系,为光学技术和生物传感器方向提供有益参考。

We analyzed the Localized surface Plasmon resonance（LSPR） of Au urchin nanostructures with Finite-Difference TimeDomain（FDTD） method by controlling the size,the distribution of nanotips and background index.The results of the FDTD calculation will lead to a better understanding of the relationship between the hierarchical nanostructures and the local surface plasmon resonance,providing a useful reference for the optical technology and biological sensors.
