Fig. 2From: Coupled Resonance Enhanced Modulation for a Graphene-Loaded Metamaterial AbsorberAbsorption spectra at the normal incidence with different EF at φ = 0, showing large blueshift of the peaks with increasing EF (a), and with different φ at EF = 0.2eV, demonstrating a polarization independence (b). The polarization angle φ is defined as in Fig. 1aBack to article page
