摘要：

Z-type barium ferrite flakes were prepared for use as fillers in electromagnetic attenuation composites. The composites with the flaky fillers exhibit greatly enhanced complex permeability, thus achieving an ultrabroad attenuation bandwidth. mu(')(0) and mu(')(max) are enhanced by above 150%, and the relative bandwidth W(R) of 6-7 can be achieved. The bandwidth achieves 75% of the theoretically maximum relative bandwidth. The composites with the flaky fillers are powerful and potential candidates as electromagnetic attenuation materials with ultrabroad bandwidth in L, C, and S bands.
