摘要
Based on the microwave absorption properties and the micro-current attenuation mechanism for the cage-like ZnO/SiO(2) nanocomposite reported in our previous paper, we established a micro-current attenuation model and the associated quantitative formula for the calculation of microwave absorption properties. Very good correlation between the calculated and the experimental results has been obtained for a broad range of frequencies. The maximum deviation less than 3 dB in X-band was obtained. The model provides useful information for understanding the microwave absorption mechanism. (C) 2008 American Institute of Physics. [DOI: 10.1063/1.3006008]
