We have analyzed the effect of various system parameters and external time-dependent field on the transport properties of monolayer graphene-based double-barrier(well) structures under a time-periodic potential. Results indicate that the Klein tunneling still exists. Besides, the transmission probability, conductivity, shot noise, and Fano factor exhibit various types of oscillatory behavior with changes in the system parameters, and they are either improved or suppressed in the presence of the time-periodic potential. We have also discussed the reasons underlying these phenomena. The results obtained in this study demonstrate that the transport properties can be controlled by manipulating the structural parameters of the system and the external field strength.
