Notes:
The electromagnetic wave absorption properties of amorphous alloy-epoxy compositeshave been investigated utilizing various amorphous alloy particle sizes in quasi-microwavefrequency. The composite fabricated with small sized particle (〈 26 μm) only revealed goodabsorption properties above 20dB with a thin thickness less than 6 mm. As particle size decreased,absorber had thinner matching thickness mainly due to increasing matching frequency. Such avariation of matching frequency was resulted from resonance frequency variation. The magneticrelaxation of the composites with small particle (〈 38 μm) was contributed to magnetic resonanceinduced by demagnetization field. The eddy current also affected on the magnetic relaxation of thecomposites with large particle (〉 38 μm) due to their large conductivity
