Abstract
Infrared (IR) absorbers have been previously studied for use in narrow-band, multi-band, and broadband applications. Here, we investigate through synthesis and experiment a broadband absorber structure based on an electromagnetic band-gap type of metasurface. A genetic algorithm is successfully employed to optimize a structure with a single patterned Pd screen to exhibit high absorptivity over more than an octave bandwidth across the mid-IR regime.
