: In this paper, by considering a system composed of multi graphene quantum well and calculating transmission probability, two important parameters of number of quantum well and incident angle has been analyzed. Our results show that with increasing the number of quantum wells the system tends to graphene superlattice and minibands appeared. Increasing the well width decreases the transmission probability. On the other hand with increasing the incident angle and penetrating evanescent wave in barrier, band gap and transmission window for positive energies appears. We found that incident angle affects the energy position of band gap and transmission window strangly so that determines the anisotropic properties of graphene multi quantum well system.
