| Abstract: | A number of electromagnetic absorbing coating materials were prepared using iron /ferrite composite materials as absorbant.The conductivity,electromagnetic parameters and absorbing properties were measured and analyzed.The results show that the conductivity,dielectric and magnetic loss of medium and high frequency region are increased with increasing of the content of doped iron.The absorbing property of absorbing coating is best when the mass ratio of iron /ferrite is 2:8.When the reflection loss is below-10 dB,the effective frequency is between low frequency and midium frequency,and the effective band width is 4.5 GHz,and the maximum absorption is-16.63 dB. |
