英文摘要	we propose and demonstrate a scheme to enhance microwave absorption property through mesoporous structure with high regularity. the mesostructured nanocomposites, embedding gamma-fe2o3 within carbon matrix, exhibit a strong and broadband attenuation of microwave in the frequency range of 0.5-18 ghz, mainly due to the better impedance matching. c-2fe-900 exhibits strong absorption characteristics with an absorption peak of -32.0 db at 6.4 ghz. the absorption peak intensity and position can be adjusted by changing the matching thickness of the coating. reflection loss below -10 db (i.e., absorption above 90%) is obtained in the frequency range of 1.9-10.7 ghz.
