Improved analytical fit of gold dispersion : Application to the modeling of extinction spectra with a finite-difference time-domain method

We propose an accurate description for the dispersion of gold in the range of 1.24–2.48 eV. We implement this improved model in an FDTD algorithm and evaluate its efficiency by comparison with an analytical method. Extinction spectra of gold nanoparticle arrays are then calculated.
