Metasurface Design and Scattering Characteristics Analysis of Miura-Ori Folded Structure

Origami can transform the metasurface between multiple structures, changing the mechanical properties, space occupation and electromagnetic scattering characteristics of the metasurface according to the needs. In order to realize the electromagnetic scattering reduction of radar targets, this paper analyzed the design and scattering characteristics of the metasurface based on Miura-Ori folded structure. Firstly, based on the equivalent circuit model and particle swarm optimization algorithm a metasurface that can achieve 10dBRCS Reduction in C - band is designed. Based on this structure, the metasurface of Miura - Ori folded structure is designed and its electromagnetic scattering characteristics are analyzed. The simulation results verify the stealth performance of the structure. In addition, the structure can change its RCS by folding and unfolding, which can be used for stealth and camouflage of deformable targets.
