• Microwave Absorption Properties of Highly Filled Polymer Composites with Amorphous Fe–B Particles

抄録

In this study, polymer composites containing amorphous Fe–B particles with large particle size distribution were fabricated. A polymer composite of mixed particles showed a high relative permeability of μ ’_r = 9.3 at 1 GHz. In addition, the composite exhibited good microwave absorption properties (R.L. < −20 dB) in the frequency range of 0.6–1.1 GHz for absorber thickness of 2.4–4.2 mm. Thus, this polymer composite can be used for fabricating microwave absorbers that are effect in the 0.7–1.0 GHz band, and would result in microwave absorbers thinner than any other microwave absorbers reported to date.
