| 摘 要： | 研究了碳化硅网眼陶瓷的微波吸收特性,发现它比实心材料的吸波性能几乎提高了两倍以上,这种吸波性能的改善主要来自网眼结构对电磁波产生的反射、散射及干涉作用引起的衰减.孔径大小、相对密度、试样厚度等因素对碳化硅网眼陶瓷的微波吸收性能的影响进行了讨论.本工作将为低成本、高性能结构型微波吸收材料的设计提供一条新途径.

| Abstract: | Microwave absorbing property of SiC reticulated porous ceramics(RPCs) was investigated in the present work. The microwave absorbing efficiency of SiC RPCs was found to increase remarkably, compared with that of SiC materials without reticulated porous structure. This is contributed mainly to the complex electromagnetic reflecting, scattering, and interference effects within the reticulated structure. Effects of pore size, relative density and sample thickness on the microwave absorbing property of SiC RPCs were discussed. This work will develop a novel approach for the design and manufacture of structural microwave absorbing materials with high performance and low cost. |
