Converting a complex index of refraction to a complex dielectric constant
I have a material's $n,k$ file, containing the complex index of refraction for every wavelength: $n(\omega)+ i\ k(\omega)$.
Now I would like to convert it to the dielectric constants: $\epsilon_{\...

Real and imaginary parts of dielectric constant vs refractive index?
So for a complex dielectric constant $\epsilon = \epsilon_a + i\epsilon_b$, the wave vector and index of refraction are related to it through $k = \frac{\omega}{c}n$ and $n = \sqrt{\frac{\mu \epsilon}{...
