skued.film_optical_coefficients

skued.film_optical_coefficients(wavelength, thickness, n_film, n_substrate=0)

Calculate the reflection, transmission, and absorption coefficients of a thin-film (possibly on a substrate).

Parameters:

  • wavelength (float) – Wavelength of the incident radiation [nm].

  • thickness (float) – Thickness of the film [nm].

  • n_film (complex or float) – Complex refractive index of the film material.

  • n_substrate (complex or float, optional) – Complex refractive index of the substrate material.

Returns:

R, T, A – Reflection, transmission, and absorption coefficients, respectively.

Return type:

float
