In this paper, we developed an EM wave absorber having the absorption ability of more than 15 dB for port logistics RFID system by using Amorphous Metal Powder. Firstly, we fabricated EM wave absorber by using Amorphous Metal Powder and CPE(Chlorinated Polyethylene) with different composition ratios 80 : 20 wt.% and 85 : 15 wt.%. Secondly, we designed the optimum EM wave absorber using the calculated material constants obtained from measured input impedance of the samples. Therefore, EM wave absorber with absorption ability of 17.5 dB at 433 MHz when composition ratio of Amorphous Metal Powder : CPE = 85 : 15 wt.% and thickness of 5.5 mm.
