چکیده انگلیسی
Electromagnetic wave absorbing properties of SiC-foams and their composites with SiO2 as matrix are presented, including theory, numerical analysis, and results/discussion. The reflection coefficients of various SiC-foams and their composites with various dielectric parameters are calculated by numerical simulation. When SiC conductivities are in the range of 2–3 S m−1 in the case of SiC-foams, or 2–5 S m−1 in the case of composites, the minimum reflection coefficients can be obtained in the range of X-band of 8.2–12.4 GHz. These materials are light weight, heat-resistant, and good impedance match with the free space, and therefore, they are a good candidate as a wide-range frequency absorbent medium.
