We would like to do some theoretical calculations of Surface-Enhanced Raman Scattering (SERS) using COMSOL. We know that there is strong plasmon coupling in between Gold nanoparticles, and we would like to analyze the plasmon resonances in the gold nanoparticles, such as the accumulation of an electric near field at the surface. For that reason, we consider two Gold spheres of 70nm in diameter with a gold-to-gold gap distance 1.5nm. Excitation with monochromatic light (785nm) parallel to the z-axis.
The thing is that we do not know how we are going to irradiate the gold nanoparticles. For example, experimentally we have an input power 2.5mW and 20s irradiation with perpendicular, 785nm laser.
We would like to do the analysis in 3D, and we could not find any tutorial on this subject.
Looking forward to hearing from you all soon.
