title: Optimized broadband wide-angle absorber structures.
abstract: By introducing the notion of wavelength- and angle-averaged absorptance, we assess in a systematic way the possibility of achieving wide-angle absorptance in a spectral range. We determine the optimum thicknesses for which this broadband wide-angle absorption occurs for a representative example of infrared detector.
