We employ the time-dependent non-crossing approximation to study the timeaveraged conductance for a single electron transistor in the Kondo regime whenthe dot level is sinusoidally driven from its equilibrium position by means ofa gate voltage in finite bias. We find that the average conductance exhibitssignificant deviation from the monotonous reduction when the applied bias isequal to the driving frequency of the dot level. We investigate the effect ofthe temperature and the driving frequency on the observed enhancement. Weattribute this behaviour to the overlap of the satellite Kondo peaks with thesplit Kondo resonances formed at each lead's Fermi level. We display thespectral function to put our interpretation into more rigorous footing.
