为揭示电磁吸波超结构的各向同异性与其宏观部件雷达散射截面（RadarCross Section,RCS）的内在关系，本文系统研究了典型的各向异性六边形蜂窝（Hexagonal Honeycomb,HH）超结构与各向同性面状Gyroid（Sheet Gyroid,SG）超结构在低雷达散射部件设计中的应用。通过采用保角映射和非保角映射设计电磁吸波超结构曲面部件，并结合仿真计算与微波暗室测试，对比了不同方法设计的曲面部件RCS。结果表明，各向同性面状Gyroid曲面部件，其RCS对设计方法不敏感，展现较强吸波能力鲁棒性；而各向异性六边形蜂窝曲面部件，其RCS对设计方法表现出强烈的依赖性。与各向异性结构相比，具备电磁各向同性的超结构在实现曲面部件广角、稳健的低散射特性方面更具优势，其性能对设计和加工的依赖性更低，为开发高性能雷达吸波部件提供了重要的设计依据。To reveal the correlation between the anisotropy of electromagnetic absorbing metastructures and the radar cross section (RCS) of its curved components, the typical anisotropic hexagonal honeycomb (HH) metastructure and isotropic sheet gyroid (SG) metastructure are systematically studied. Then, both conformal mapping and non-conformal mapping methods were employed for designing the conformal curved components. These designs were compared using simulation and microwave anechoic chamber testing to evaluate their RCS. The results indicate that the RCS of isotropic sheet gyroid curved components are insensitive to design methods, demonstrating strong design method and absorbing robustness; however, the RCS of anisotropic hexagonal honeycomb curved components exhibit strong dependence on design methods. Compared to anisotropic structures, metastructures with electromagnetic isotropy offer significant advantages in achieving wide-angle and robust low-scattering characteristics for curved components, with lower dependence on design and processing. This study provides important design guidance for developing high-performance radar low-scattering components.
