This code computes the complex dielectric constant (i.e. relative permittivity) and the refractive index of various metals using either the Lorentz-Drude (LD) or the Drude model (D) as a function of input light wavelength.

Additionally, it may compute the dielectric constant of pure water using a Debye-Lorentz model.

Choice of materials: silver, aluminum, gold, copper, chromium, nickel, tungsten, titanium, beryllium, palladium, platinum, triply distilled water.
