Micro-current attenuation modeling and numerical simulation for cage-like ZnO/ SiO2 nanocomposite

Abstract

Based on the microwave absorption properties and the micro-current attenuation mechanism for the cage-like ZnO/ SiO2 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. © 2008 American Institute of Physics.
