Abstract
This work presents a strong microwave absorber with Koch fractal activated carbon fiber (ACF) felt screens. The effects of arrangements (spacing d) and structure parameters (iteration number n, initial side-length L) of Koch fractal units on the microwave absorption (MA) properties were investigated. It was observed that the optimal spacing d was obtained at 20Â mm, and the reflection loss (RL) decreased in the low frequency-range from 6 to 9Â GHz, but increased in the high-frequency range from 16 to 18Â GHz apparently with increasing n and L. The strongest MA could reach - 62.8Â dB. The relationship between ACF area ratio and RL was described.
