Conventional experientialism-inspired and intuition-inspired research on microwave-absorbing (MA) materials appears to lack efficiency. The present work aims to establish a scalable parametrization-design methodology for multifunctional coupled MA metamaterials involving up-front theoretical calculation and simulation predictions followed by experimental verification. A top-down parametrization-design methodology is proposed herein, which relies on the utilization of polymer-derived ceramics (PDCs) with flexible electromagnetic tunability as substrate materials, combined with tunable electromagnetic response via mathematical modeling of triply-periodic-minimal-surfaces shellular structures. In the process, preferred structural configuration and orientation are screened with actual requirements while final fabrication in a single step is enabled by 3D printing technology. The effect of structural configuration and orientation on electromagnetic response is scrutinized and a novel optimization method for deterministic high-temperature MA properties is proposed. As-fabricated [111]-oriented Gyroid shellular MA metamaterials exhibit superior overall performance in the X-Ku band with wide-temperature adaptability. At room temperature, the minimal reflection loss (RL_min) value is –58.05 dB, effective absorbing bandwidth (EAB) with RL ≤ –10 dB reaches 6.11 GHz, and the specific strength reaches 65.20 MPa/(g/cm³) at the ultralow density of 0.550 g/cm³. RL_min improves to –72.38 dB at 100 °C while EAB increases to 6.77 GHz at 300 °C and retains 5.60 GHz at 600 °C.

对微波吸收 (MA) 材料的传统经验主义启发和直觉启发研究似乎缺乏效率。目前的工作旨在为多功能耦合 MA 超材料建立一种可扩展的参数化设计方法，涉及前期理论计算和模拟预测，然后进行实验验证。本文提出了一种自上而下的参数化设计方法，该方法依赖于利用具有柔性电磁可调性的聚合物衍生陶瓷 (PDC) 作为基板材料，并通过三重周期最小表面壳层的数学建模结合可调谐电磁响应结构。正在进行中，首选的结构配置和方向根据实际要求进行筛选，而最终制造则通过 3D 打印技术一步完成。研究了结构配置和方向对电磁响应的影响，并提出了一种确定性高温 MA 特性的新型优化方法。制造的 [111] 取向 Gyroid 壳状 MA 超材料在 X-Ku 波段表现出优异的整体性能，具有宽温适应性。在室温下，最小反射损耗（制造的 [111] 取向 Gyroid 壳状 MA 超材料在 X-Ku 波段表现出优异的整体性能，具有宽温适应性。在室温下，最小反射损耗（制造的 [111] 取向 Gyroid 壳状 MA 超材料在 X-Ku 波段表现出优异的整体性能，具有宽温适应性。在室温下，最小反射损耗（RL _min )值为–58.05 dB，有效吸收带宽(EAB) RL ≤ –10 dB达到6.11 GHz，比强度在0.550 g/cm ³超低密度下达到65.20 MPa/(g/cm ³ ) 。RL _min在 100 °C 时提高到 –72.38 dB，而 EAB 在 300 °C 时提高到 6.77 GHz，并在 600 °C 时保持 5.60 GHz。
