摘要	Currently, the performance of common radar absorbers deteriorates dramatically at elevated temperatures, which limits their application in high -temperature environments. Here, a heat -resistant ceramic metamaterial (CMM) was designed and fabricated for broadband microwave absorption. Compared with conventional metalbased metamaterials, the proposed CMM shows better heat endurance due to the excellent chemical stability of titanium diboride (TiB2) and silicon carbide nanowires (SiCnws) at high temperature. In the CMM, which exhibits excellent electromagnetic (EM) wave polarization stability properties, the SiCnws coatings are covered by twodimensional periodically aligned circular plates of conductive TiB2. With the modulation of geometric parameters, such as the size and period of the unit cell and the thickness of the SiCnws coatings, the optimized CMM with an effective absorption bandwidth (EAB) of 6.3 GHz was achieved by calculation. At the same time, corresponding experimental samples were prepared and measured. It was shown that the measured reflectivity curve agreed well with the simulated one at a period of 15 mm, achieving a broad EAB of 4.9 GHz. Moreover, the EM absorption mechanism and the oblique incidence absorption properties were systematically investigated. Benefiting from the excellent integrated properties, the as -prepared high -temperature resistance CMM shows great promise for electromagnetic protection applications.
