Abstract

Infrared (IR) metamaterial absorbers have been previously studied for use in narrow-band, multi-band, and broadband applications. Here, we investigate 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 of bandwidth across the mid-IR. The final design is fabricated and characterized to validate the simulation results.
