Hi everyone
When I Add a new Material from the library (e.g. Pd or Cu), then I can see its real and refractive indexes, n and k respectively.
They function n which is a function of the wavelength is calculated automatically using a local table. The function is called n_interp for the real part.
Now when I want to use the refractive index in an expression (e.g. as an expression under "derived values") I don't know how to access this function.
I would like to write an expression like
n_interp_Pd(lambda) / n_interp_Cu(lambda)
But as the refractive index of Cu is calculated similarly and the interpolation function of Cu is also just called n_interp, I don't know how to access these two functions.
I solved the problem creating two interpolation functions under "global definitions" where I copied the local tables from Pd and from Cu and called them n_Cu and n_Pd. Now I can access these functions.
But I think this step is unnecessary since these functions are exact copies of already existing functions...
Does somebody know how to avoid this additional step?
Best regards
Gabriel

Aaah now I found it:
When you would insert an expression, just hit the + sign (insert expression) and go to
Model/Definitions/Material functions
There you find all the interpolation functions.

Can you explain for me more detail about how we can access to function n_interp. Thank you !
