Abstract
Infrared (IR) absorbers have been previously studied for use in narrow-band and multi-band applications. Here, we investigate a broadband absorber structure comprised of multiple, stacked frequency selective surface screens. A genetic algorithm is successfully employed to optimize a structure with three Au screens to exhibit high absorptivity across the mid-IR range from 3 μm to 5 μm.
