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: I. Timrov, N. Vast, R. Gebauer, and S. Baroni, "Electron energy loss and inelastic x-ray scattering cross sections from time-dependent density-functional perturbation theory", Phys. Rev. B 88, 064301 (2013); ibid. 91, 139901 (2015). and I. Timrov, N. Vast, R. Gebauer, and S. Baroni, "turboEELS - A code for 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).
