| Abstract: |
| The chemical-bond characteristic,micro-structure and electromagnetic parameters were investigated by means of FT-IR,SEM and vector network analyzer. The results show that the vinyltrimethoxysilane integrates asymme- try deposits on the surface of the carbonyl iron powder, the electromagnetic parameters are variable as the quantity of si- lane coupling agent increases. According to the electromagnetic parameters, the absorbing property of carbonyl iron powder was computed. When the quantity of vinyltrimethoxysilane is 2.0%, the radar absorbing property is best, the frequency range with reflectivity under- 10 dB is from 5.2 GHz to 10.0 GHz. |
