AbstractFoam structure materials are well known for their lightweight, efficient, and broadband microwave absorption properties compared to bulk material. However, little has been understood about the effect of a foam structure on the absorption performance of the foam material. In this study, the role of foam structure properties of the silicon carbide/carbon (SiC/C) foam material on microwave absorption is explored using experiment and simulation. We find that the foam structure of SiC/C foam material causes diffraction, multiple reflections, improves the interfacial polarization, and compatibilization. The absorption performance of SiC/C foam material is also studied. The -10 dB effective absorption bandwidth can be adjusted from 4.0 GHz to 18 GHz by tuning SiC/C foam material thickness to 3-7 mm. Therefore, the foam structure design is an effective way to improve the absorption performance of the SiC/C foam material.
