Abstract

The reflection loss (RL) properties including the frequency, intensity, and bandwidth of absorption peaks for the flake-shaped carbonyl-iron particle/paraffin composite were investigated in detail. By measuring the reflection coefficient of the composite without (S11-OPEN) and with (S11-SHORT) a backed metal plate, the origin of the RL peak was directly verified. The separated electromagnetic wave energy reflected at the air-absorber interface and the absorber-metal plate interface was achieved from S11-OPEN and S11-SHORT parameters, and they were used to explain the intensity variation of the RL peak. The bandwidth of the RL peak was also deduced from viewpoint of interface reflection waves. The calculated bandwidth from the derived formula agreed well with the experimental data.
