We proposed a two-layer metamaterial structure with graphene that consists of two H-shaped resonators and one I-shaped resonator. The electromagnetically induced absorption (EIA) analog phenomena were observed in absorption spectra, resulting from the near-field coupling of two bright modes. Furthermore, the absorption peak can be tuned by changing the dimension of the I-shaped resonator or changing the Fermi energy of graphene. The theoretical analysis reveals that the EIA analog arises from magnetic resonance using the coupled Lorentz oscillator model. This hybrid-EIA analog structure may provide a possible choice for designing potential devices for dynamic narrow-band filtering and absorber applications.
