This study proposes a method for providing electromagnetic function by arranging patterns three-dimensionally on honeycomb partition walls. A conductive paste is thinly printed to fabricate a resistance component. To increase the current path induced by the incident electromagnetic waves, a rectangular pattern with an aspect ratio is used to further generate electromagnetic losses. Rectangular patterns are arranged alternately to ensure the homogeneity of the entire honeycomb medium. The proposed honeycomb achieved excellent absorption performance in the C, X, and Ku bands, regardless of the polarization. Simulations were used to show that the microwave-absorption performance of a honeycomb with a three-dimensional pattern could be estimated analytically. The obtained results were compared with those of other studies. The proposed honeycomb was effective in reducing the broadband monostatic radar cross section when applied to the leading edge of a wing box.

一种轻质、灵活且对偏振不敏感的微波吸收蜂窝芯，利用印刷周期图案中的传导损耗

这项研究提出了一种通过在蜂窝隔墙上三维排列图案来提供电磁功能的方法。薄薄地印刷导电膏以制造电阻元件。为了增加由入射电磁波感应的电流路径，使用具有纵横比的矩形图案来进一步产生电磁损耗。矩形图案交替排列，保证整个蜂窝介质的均匀性。无论偏振如何，所提出的蜂窝在 C、X 和 Ku 波段都实现了出色的吸收性能。模拟结果表明，具有三维图案的蜂窝体的微波吸收性能可以通过分析方法进行评估。将获得的结果与其他研究的结果进行了比较。当应用于翼盒的前缘时，所提出的蜂窝结构可有效减少宽带单基地雷达横截面。
