摘要
随着对未知和极端环境的不断探索，增强无源器件的温度稳定性变得尤为重要。本研究采用融合设计方法，将基于稀有金属的钨青铜结构陶瓷和超材料结合在一起，开发出一种具有超强温度稳定性的陶瓷基超材料吸收器。具体来说，基于米氏共振的元材料阵列在波导和自由空间中的吸波率都超过了 49.0%，接近理论极限。根据阻抗分析，吸收性能与介质损耗（Qf）有明显的相关性。值得注意的是，高温稳健性在 400 °C 时仍然有效。我们设计中的这些进步使得使用单片材料制造温度稳定的完美吸收体成为可能，从而为介电性能提供了更大的自由度，并拓展了其潜在应用领域，包括太空探索和 5G 毫米波应用场景。
Ceramic-based meta-material absorber with high-temperature stability
With the continuous exploration of uncharted and extreme environments, enhanced temperature robustness of passive devices has become particularly important. In this study, a ceramic-based meta-material absorber with exceptional temperature stability is developed using a fusion design approach that combines rare metal-based tungsten bronze structural ceramics and meta-materials. Specifically, the absorbance of the meta-material array based on Mie resonance exceeds 49.0% in both waveguides and free space, approaching the theoretical limit. According to impedance analysis, the absorption performance can be distinctly correlated with the dielectric loss (Qf). Notably, the high-temperature robustness is verified to still be effective at 400 °C. These advancements in our design allow for the use of monolithic materials in fabricating temperature-stable perfect absorbers, providing greater freedom in the dielectric performance and expanding their potential applications, including in space exploration and 5G millimeter-wave scenarios.
