The absorbers consist of four main layers: a metal back plate, dielectric spacer, and two artificial layers. One of the artificial layers provides electrical resonance and the other one provides magnetic resonance yielding a polarization independent broadband perfect absorption. The structure response remains similar for the wide angle of incidence due to the sub-wavelength unit cell size of the constituting artificial layers. The design is useful for applications such as thermal photovoltaics, sensors, and camouflage. ©2011 Optical Society of America.EnglishInfrared devicesMagnetic resonancePlate metalDielectric spacersNear InfraredNear-infrared bandsPhotovoltaicsPolarization independentResonant absorberStructure responseSub-wavelengthThin absorbersUnit cell sizeWide anglePolarizationArticle10.1364/OE.19.014260
