Abstract

Plasmonic metamaterial is a new class science which can regulate the electromagnetic response characteristics, including frequency, phase and polarization characteristics, by the specific design of structure and distribution of materials. But how to design the structure and material effectively becomes a issue worth studying. Inverse design has experienced rapid development in the past 20 years. When we applied some algorithms into the design of metamaterial, the efficiency can be improved greatly. In this paper, we proposed and improved a fully automatic genetic algorithm for the optimization of polarization-selective broadband absorber for 3μm-5μm, and we successfully achieved an average absorption of up to 0.7522 in 3-5um for transverse magnetic wave.
