In this work, we consider the numerical solution of a metamaterial structure consisting of graphene in which two graphene split-rings are on a dielectric. Actually, the destructive interaction created in this structure between the two bright-bright plasmonic modes leads to stimulated transparence in spectral responses. In fact, space of the two rings plays a key role that we can create a frequency transmission for the created resonance by increasing and decreasing of this space. This frequency transmission through the gap space is equal to 0.4 THz. Furthermore, by changing the graphene input voltage and changes in the chemical doping of graphene we can control the scope of this clear aperture which its frequency transmission is equal to 6 THz. So in two ways, we created the space of the gap in the rings and chemical potential of resonance range control. Applications created from this type of structure are in light switches, light slowing and biosensors.
