Abstract

The permeability and reflection loss of the composites filled by water-atomized amorphous-ferroalloy particle are investigated in the range of 1-18 GHz. The results show that the granular size strongly influences the permeability and absorbing property of the material. The soft magnetic property of the particle of 10 μm which is of the order of the skin depth differs from that of 40 μm particle. The Bruggeman effective medium theory can well predict the dynamic magnetic properties in high frequency region for the materials. The composite with the 10 μm particle shows excellent performance in high-frequency absorption compared to the one with the bigger size particle. The size-selectable amorphous-ferroalloy particle is one of the promising candidates for microwave absorption applications.
