Abstract

The finite-difference time-domain (FDTD) algorithm is applied to analyze the electrical properties of gold films, whose relative permittivity is described by the Lorentz-Drude model in infrared and optical frequencies. The skin depth and reflectivity are calculated using the frequency-dependent FDTD method. The results are compared to analytical solutions and an excellent agreement is reported.
