incident obliquely are localized except for in some special cases. This phenomenon is an extension of the famous Klein tunneling to random cases.[@klein; @kats2] Another interesting and counterintuitive feature is that localization is destroyed as the strength of the scalar potential disorder increases to large values.[@fang]

The localization behavior of Dirac particles incident normally on a 1D random scalar potential was studied numerically for the first time in Ref. 35, where it has been demonstrated that, in the massless case, the localization length diverges and, in the massive case, it is larger than the corresponding nonrelativistic value. The transmission of electron waves through disordered Graphene superlattices with a random scalar potential was studied in Ref. 36. The transmittance of a finite strip was shown to be equal to 1 at normal incidence and to have a strong angle dependence at oblique incidence. In Ref. 37, analytical formulas for the localization length in disordered graphene superlattices with a random scalar or vector potential were obtained using the transfer matrix method and the weak-disorder expansion. The localization length was reported to have a $\tan^{-2}\theta$ dependence on the incident angle $\theta$ for all energy in a weak scalar potential and to have a
