N2 - Nowadays, many communication devices use GHz-range microwaves, which cause serious issues, such as electromagnetic interference. For the prevention of these problems, microwave absorbers consisting of polymer composites with magnetic particles have received attention. With the current trend being to miniaturize devices, thin microwave absorber are now required. This paper reports that polymer composites with amorphous Fe-B submicrometer particles and Ni-Zn-Co ferrite nanoparticles showed a permeability of μr′ = 8.0-9.0 at 1.0 GHz and a resonant frequency of f r = 1.8-2.4 GHz. They also exhibited good microwave absorption properties at 0.7-1.4 GHz for thicknesses of 2.5-3.9 mm.
