| Popis: | A novel iron-coated carbon fiber has been fabricated by electrochemical method. Magnetic properties, complex permeability, and complex permitivity have been measured. It is found that the sample has a low coercive force. By doping a few fibers to general absorbers (carbonyl iron), the complex permeability and permitivity of composites achieved a rise without the obvious increase of filling density. This result shows that the doping of fibers to general absorber will effectively decrease the thickness of the microwave absorption layer. |
