Microwave Absorbing Property of SiC Reticulated Porous Ceramics
碳化硅网眼多孔陶瓷的微波吸收特性

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.
