We report a wide-angle polarization-sensitive dual-band absorber with a grating structure. The unit cell is made of two metal–dielectric–metal structures with different dielectric-layer thicknesses. The simulation results show that the dual-band absorption peaks for TM polarization can be tuned by varying the thickness of the dielectric layer. Also, the dual-band absorption magnitudes are more than 0.9 for both absorption peaks for angles up to 60°. At the same time, TE-polarized light has been reflected effectively in the visible and infrared regimes. Our results may have potential applications in polarization detectors and reflective polarizers.
