This paper unveils a pioneering ultra-wideband metasurface, achieving both optical transparency and significantly reduced scattering, surpassing current stealth material limitations. A novel dual-layer meta-atom, expertly balanced for polarization conversion absorption, is meticulously fine-tuned through equivalent circuit analysis sophisticated genetic algorithm, targeting broad operational bandwidth. By ingeniously arranging these meta-atoms alongside their mirrored twins, we facilitate an efficient redistribution of scattered cross-polarized energy, leading to substantial reductions in radar detectability. Simulation validations experimental results affirm marked improvement performance, characterized by co-polarized RCS reduction excess 10 dB across the extensive 3.7–25.9 GHz band. groundbreaking metasurface offers versatile solution wideband electromagnetic control aerospace, telecommunications, applications, pushing boundaries technology.
