refind.n_metal_model(wl, epsinf, lp, gp, *poles)

Use the model presented in Etchegoin et al., J Chem Phys 125, 164705 (2006) to describe the refractive index of nobel metals using a combination of Drude and Lorentz models.

Parameters:

• wl (array) – Wavelength axis in um.
• epsinf (float) – High frequency limit of permittivity.
• lp (float) – Plasma wavelength for Drude model (same units as wl).
• gp (float) – Damping term for Drude model (same units as wl).
• poles (mixed) – Parameters for Lorentz poles. For each pole provide (amplitude, phase offset, resonance wavelength and width).

Returns:

Complex refractive index (same shape as wl).
