Origami electromagnetic (EM) structures are promising technologies for deployable and reconfigurable EM structures such as antennas and frequency-selective surfaces (FSSs). However, these structures present CAD modeling difficulties due to their complex geometries. Studying the effects of origami substrate folding on EM performance demands multiple CAD models at different fold angles. Also, optimization of such structures for desired EM performance requires analysis of many CAD models. To enable fast CAD modeling, we introduce a toolset for automated modeling of origami EM structures. The proposed toolset uses origami mathematics for generating thin origami models. The thin models are then converted to thick substrates with conductive regions by implementing additional mathematical algorithms. Automated CAD modeling is achieved using Visual Basic Scripting (VBS) of the entire design and simulation process in Ansys high-frequency structure simulator (HFSS) using MATLAB. This toolset is important for future research of origami EM structures because it enables automated CAD modeling and optimization.

折纸电磁结构的自动化设计和优化[EM程序员的笔记本]

折纸电磁（EM）结构是用于可部署和可重新配置EM结构（例如天线和频率选择表面（FSS））的有前途的技术。但是，由于其复杂的几何形状，这些结构存在CAD建模困难。要研究折纸基材折叠对EM性能的影响，需要在不同折叠角度使用多个CAD模型。同样，为获得所需的EM性能而优化此类结构还需要分析许多CAD模型。为了实现快速的CAD建模，我们引入了一个工具集，用于对折纸EM结构进行自动建模。拟议的工具集使用折纸数学生成薄折纸模型。然后，通过实施其他数学算法，将薄模型转换为具有导电区域的厚基板。使用MATLAB在Ansys高频结构仿真器（HFSS）中使用整个设计和仿真过程的Visual Basic脚本（VBS），可以实现自动CAD建模。该工具集对折纸EM结构的未来研究非常重要，因为它可以实现自动CAD建模和优化。
