We examine the transmissions in gapped graphene through a combination of double barriers tilting and time-oscillating potential. The latter introduces extra sidebands to the transmission probability, which occur at energy levels determined by the frequency and incident energy. The sidebands are generated as a result of the absorption or emission of photons yielded from the oscillating potential. Our results indicate that transmission probabilities in gapped graphene can be manipulated by regulating the incident energy, the oscillating potential, or the distance between two barriers and their heights. It has been observed that the transmissions may be impeded or prevented by tuning the gap.
