Abstract

Microwave absorption presents a challenge for the design of metamaterials, which is critical for the stealth and electromagnetic compatibility. To address this, a novel design strategy for patterns is proposed to enhance the wave absorption, which is tortuosity and connectivity. Utilizing the carbon ink composite and genetic algorithm, multi-layer coding metamaterials (MCMs) are designed to satisfy diverse engineering specifications, with reflectivity tests confirming their efficacy. Temperature alternation experiments simulate frequent environmental changes, and the absorptivity of MCMs is compared to evaluate their resilience. This approach ensures the designed MCMs maintain performance and stability under variable thermal conditions, offering a robust solution for advanced applications.

具有曲折性和连通性的微波吸收编码超材料的图案设计策略

微波吸收对超材料的设计提出了挑战，而超材料的设计对隐形和电磁兼容性至关重要。为解决这一问题，我们提出了一种新颖的图案设计策略，即迂回性和连通性来增强吸波能力。利用碳墨复合材料和遗传算法，设计出了多层编码超材料（MCMs），以满足不同的工程规范，并通过反射率测试证实了其功效。温度交替实验模拟了频繁的环境变化，并比较了 MCM 的吸收率，以评估其复原能力。这种方法可确保所设计的 MCM 在多变的热条件下保持性能和稳定性，为先进的应用提供稳健的解决方案。
