Abstract： We study the transmission dynamics of a driven two-level system
dissipated by the two leads. Using nonequilibrium Green function, we derive an analytical transmission formula for an electron incident from the left lead, through the double quantum dots, to the right lead. Landauer-type conductance and current are also given. A discussion of the internal tunneling dynamics reveals crucial effects of the localization and delocalization on the transport of the system.
