From: A multiband perfect absorber based on hyperbolic metamaterials
Polarization independent perfect absorption (a) Absorption spectra of Pd GC-Ag/TiO2 HMM at different angles of incidence and (b) Absorption spectra of Pd GC-Ag/TiO2 HMM for TM and TE polarization. Wide angle, multiband and polarization independent broad perfect absorption is possible.
