Dear Eliya Asmani,

First of all, please sign your posts with your name and affiliation!

The turboEELS code of TDDFPT may probably be of interest for you. It 
allows one to calculate the susceptibility as a function of frequency 
and transferred momentum for periodic systems. More details can be found 
in these publications:

inelastic x-ray scattering cross sections from time-dependent 
density-functional perturbation theory", Phys. Rev. B 88, 064301 (2013); 
ibid. 91, 139901 (2015).

the simulation of the electron energy loss and inelastic X-ray 
scattering spectra using the Liouville-Lanczos approach to 
time-dependent density-functional perturbation theory", Comp. Phys. 
Commun. 196, 460 (2015).
