This paper presents an origami metamaterial designed for ultra-wideband and large-depth reflection modulation, addressing the limitations of existing dynamic devices such as narrow bandwidth and limited modulation range. By fusing origami techniques with metamaterial design, the proposed metamaterial achieves over 10-dB modulation depth over a frequency range of 4.96 – 38.8 GHz, with a fractional bandwidth of 155% and tolerance to incident angles and polarizations. The metamaterial's performance is verified through experiments and analyzed using multipole decomposition theory. To enhance practical applicability, transparent conductive films are introduced, achieving high optical transparency (>87%) from visible to near-infrared light while maintaining cost-effectiveness. The design's lightweight, foldability, and low cost make it promising for satellite communication and optical window mobile communication management applications. The study also explores the influence of different geometrical parameters on the reflection modulation performance and demonstrates the metamaterial's stability under oblique incidence and polarization conditions. The proposed origami metamaterial offers significant improvements in operational bandwidth and modulation depth compared to other dynamic metamaterials, making it a practical solution for space communication and other applications requiring transparency and dynamic modulation capabilities.This paper presents an origami metamaterial designed for ultra-wideband and large-depth reflection modulation, addressing the limitations of existing dynamic devices such as narrow bandwidth and limited modulation range.
