Modeling of regular gold nanostructures arrays for SERS applications using a 3D FDTD method

Abstract : We study the localized surface plasmon resonance (LSPR) and the surface-enhanced Raman scattering (SERS) of arrays of gold cylindrical and ellipsoidal nanoparticles with different diameters or major axes. The LSPR and SERS gains are calculated with the three dimensional Finite-Difference Time-Domain method using the Drude–Lorentz dispersion model. We find that the maximum of the extinction spectrum and the average SERS gain of each investigated nanostructures are shifted whatever their size and their shape.
