Absorption spectra with different polarization angles (φ) and incident angles (θ) and frequency of the incident wave from 0 to 12 THz: (a–c) broadband absorption when μc = 0.8 eV and VO2 is in an insulator state; (d–f) dual-band absorption when μc = 0.8 eV and VO2 is in a metallic state; (g–i) single-band and relatively narrow absorption when μc = 0 eV and VO2 is in a metallic state.
