摘要

优化阻抗匹配是提高电磁吸波材料性能的关键。本研究利用不同相邻光斑距离的飞秒激光（fs）在SiCf/SiCN复合材料上制备了具有组分梯度和结构梯度的梯度阻抗匹配层。结果表明，当光斑距离为30 μm时，该材料的电磁波吸收效果最佳，反射系数最小（rmin）为- 15 dB，厚度为2.05 mm，在9.9 GHz频率处的吸收性能达到96.8%，在uv - nir波段的吸收性能达到82%。这是由于适当的相邻光斑距离使得激光照射的SiCf/SiCN复合材料表面可以从结构和成分上形成纳米颗粒附着的沙丘状周期性结构，从而调节阻抗匹配。此外，激光诱导的缺陷和纳米非均质界面增加了极化损耗。本研究为研究SiCf/SiCN复合材料的多谱电磁波吸收特性提供了一种新的技术途径。

Femtosecond laser induced the graded impedance matching structure to achieve multi-spectrum EM wave absorption performance

Optimal impedance matching is crucial for enhancing the performance of electromagnetic (EM) absorbing materials. In this study, a gradient impedance matching layer with component gradient and structural gradient was prepared on SiC_f/SiCN composites by femtosecond laser (fs laser) with different adjacent spot distance. The results show that the EM wave absorption is optimal when the spot distance is 30 μm, possessing the minimum reflection coefficient (RC_min)of −15 dB with a thickness of 2.05 mm, and the absorption performance at the frequency of 9.9 GHz reaches 96.8 %, while the absorption in the UV-to-NIR ranges reaches 82 %. This is attributed to the appropriate adjacent spot distance which allows the fs laser irradiated SiC_f/SiCN composites surface to build nanoparticle-attached dune-like periodic structures from the structure and composition together regulating the impedance matching. In addition, fs laser induced defects and nano-heterogeneous interfaces enhance the polarization loss. This study provides a new technological approach to the multi-spectrum EM wave absorption properties of SiC_f/SiCN composites.
