Aerodynamic and electromagnetic analysis of a Rubik's cube-inspired origami structure

During the launch and orbital flight of a spacecraft, spatial limitations require the modification and optimization of antennas to guarantee optimal electromagnetic wave transmission and aerodynamic efficiency. This study, inspired by the Rubik's Cube, presents a novel origami structure that, through precise geometric control, facilitates the integration of fluid management and electromagnetic signal transmission, thereby enabling the efficient consolidation of multifunctional systems such as gas analysis and communication within confined spaces. The study initially examines the design configuration of the Rubik's cube-inspired origami structure and analyzes the fluid control efficacy of integrating non-reciprocal devices with check valves, as well as the performance of the electromagnetic antenna design incorporated within the structure. It also evaluates the impact of crease geometry on the deformation process of the origami structure and investigates how this deformation affects the transmission characteristics of electromagnetic waves across various frequencies. This study offers both theoretical and empirical evidence for the optimization of origami structures in signal transmission and aerodynamics, illustrating their extensive applicability to platforms like foldable microfluidic antennas and origami-deployable multifunctional spacecraft walls.
