In this study, polymer composites containing amorphous Fe-B submicrometer particles and Ni–Zn ferrite nanoparticles were fabricated. A polymer composite of mixed particles showed high permeability of μ′r=13.7μ′r=13.7 at 0.5 GHz and μ″r=8.3μ″r=8.3 at 1.2 GHz. In addition, this composite exhibited good microwave absorption properties (R.L. < −20 dB) in the frequency range of 0.65–1.12 GHz for absorber thickness of 2.38–4.06 mm. It is concluded that this polymer composite can be used for fabricating microwave absorbers in the UHF range, and would result in thinner microwave absorbers than any other microwave absorbers reported thus far.
