Abstract
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.
