摘要：

The Klein tunneling of Dirac fermions through a symmetric double potential barrier of a rectangular shape in graphene has been investigated. A new analytical formula for a dependence of the transmission coefficient of electrons on the angle of incidence on the barrier was obtained, on the basis of which the conditions for the angles of incidence with 100% transmission were found. In the case of a double potential barrier we have three conditions for resonance tunneling, two of which are similar to those conditions for one barrier, and the third one reflects the presence of the second barrier.
