Fig. 2 (Color online) Schematic representation of the double-period sequence-built structure as stacking of dielectric layers incorporating graphene. The sequence generation number (\(m\)) varies from 0 to 2. $H$ and L denote the high and low refractive index material, respectively and G represents the graphene thin layer.
