This study presents an origami metamaterial that enables ultra-wideband and large-depth reflection modulation. The metamaterial is designed using origami techniques and flexible electronic materials, achieving a modulation depth of over 10 dB over a 155% fractional bandwidth from 4.96 to 38.8 GHz. It is also transparent to visible and near-infrared light, with an average transmittance of over 87.2%. The structure is lightweight, foldable, and low-cost, making it suitable for satellite communication and optical window mobile communication management. The metamaterial's performance is verified through experiments and analyzed using multipole decomposition theory. The design is also robust to incident angles and polarizations, and its practical applicability is enhanced by the use of transparent conductive films. The structure's mechanical properties are analyzed, showing a negative Poisson's ratio and high foldability. The metamaterial is fabricated using micro-precision laser etching and is significantly cheaper than other dynamic metamaterials, with a cost of 16/m². The study highlights the potential of origami metamaterials for dynamic modulation applications in space communication and other fields.This study presents an origami metamaterial that enables ultra-wideband and large-depth reflection modulation.
