Inverse Design of Diffusion–Absorption Hybrid Metasurfaces

Zicheng Song, Ruicong Zhang, Pingping Min, Tianyu Wang et autres

Abstract Random metasurfaces have demonstrated significant potential in radar‐signature control applications, but their ability to manipulate scattering‐field reduction is limited by relying solely on the diffusion mechanism. To achieve flexible and arbitrary designs for scattering‐field reduction, a diffusion–absorption hybrid metasurface is proposed …
