Hi Stefan, no, you do not have to find any "physically correct" set of polarizability parameters. Once that they fit the dielectric function, they produce the same polarization as the dielectric function, therefore they work. For the other question after reading quickly through your code I wasn't able to identify the problem. But if you do tests on your code that have the purpose of finding out why it doesn't work with E_x (unless I am missing something important) you could decrease a bit the resolution.
