本文提出了一种基于拓扑优化方法的局部表面等离子体共振金属纳米结构的逆设计方法。利用所提出的方法，实现了表面增强拉曼光谱在纳米结构中金属分布的测定，以最大化增强因子。结果表明，该方法可用于设计在特定入射波长下具有共振峰和显著增强因子的金属纳米结构，并可通过拓扑优化来控制共振峰的位移。
This note presents an inverse design methodology of metal nanostructures for localized surface plasmon resonances, based on the topology optimization approach. Using the proposed method, determination of the metal distribution in nanostructures is implemented for surface enhanced Raman spectroscopy to maximize the enhancement factor. The obtained results demonstrate that the outlined approach can be used to design metal nanostructure with resonant peak and significant enhancement factor at specified incident wavelength, and to control the shift of the resonant peak by topologically optimizing the nanostructure.
