摘要

在航天器的发射和轨道飞行过程中，空间限制要求对天线进行修改和优化，以保证最佳的电磁波传输和气动效率。这项研究受到魔方的启发，提出了一种新颖的折纸结构，通过精确的几何控制，促进流体管理和电磁信号传输的整合，从而使多功能系统（如气体分析和有限空间内的通信）得到有效的巩固。该研究首先考察了受魔方启发的折纸结构的设计配置，并分析了将非互反装置与止回阀集成在一起的流体控制效果，以及该结构中集成的电磁天线设计的性能。它还评估了折痕几何形状对折纸结构变形过程的影响，并研究了这种变形如何影响电磁波在不同频率上的传输特性。该研究为折纸结构在信号传输和空气动力学方面的优化提供了理论和经验证据，说明了折纸结构在可折叠微流控天线和折纸展开多功能航天器壁等平台上的广泛适用性。

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.
