Abstract

The plasmonic properties of individual gold nanosponges are very interesting due to their distinct structural features, which combines both 3D and 0D characteristics [1–6]. In order to better understand the structure-property-relation, the optical properties have been simulated with Finite-Difference Time-Domain (FDTD) method [1–4]. However, due to the complexity of the porous structure, it is very difficult to build a model with the exact same percolated porous structure with mathematic methods, and the models used in literatures [1–4], were simplified and constructed with a large gold sphere etched by randomly distributed spherical air pores.
