Abstract：We study the double barrier tunneling properties of Dirac particles in spin-orbit coupled Bose–Einstein Condensates. The analytic expression of the transmission coefficient of Dirac particles penetrating into a double barrier is obtained. An interesting resonance tunneling phenomenon is discovered in the Klein block region which has been ignored before.
