[Pw_forum] dielectric constant dependence on frequency

[Andrey Chibisov]

Dear Colleagues.
I want to calculate the dielectric constant dependence on the frequency using a Phonon code.
However, in the examples there is only an example for calculating the dynamic polarizability of methane molecules 
as a function of frequency. Can I make a calculation for the dielectric constant? 
By default, I get a constant value that is more like a high-frequency value, rather than a low-frequency one.
