We investigate the interaction of proton with a solid target, describing the wake
effects by taking fitted parameters with experimental values of energy loss function ELF for copper using the dielectric function of random phase approximation (RPA). The results exhibited a damped oscillatory behavior in the longitudinal direction behind the projectile. In addition, the wake potential becomes asymmetric around the z-axis with proton velocity values higher than Fermi velocity Ʋ > ʋf, as well as it depends on the position of projectile in cylindrical coordinates .
