Summary:
We have applied the 3D Legendre pseudospectral time-domain scheme to study the optical properties of 2D plasmonic nanoparticle square arrays with different gap sizes. Numerical simulation results have been compared with a theoretical dipole model which provides quick analysis, and good agreement was obtained. The high-accuracy numerical scheme is especially suited for dealing with metal-dielectric interfaces in plasmonics problems. The more precise DrudeLorentz model has been introduced to provide a better material model and thus more accurate calculation in the wavelength region from visible to the near infrared.
