Abstract:
Radar wave absorption materials have been widely used in electron devices working in microwave frequency to avoid the electromagnetic wave interference and in military equipments to prevent the detection of radar wave. High performance radar wave absorption materials require a high permeability and appropriate permittivity in GHz range. Due to that the flakeshaped FeSiAl powder has the superior soft magnetic properties and possesses the high permeability and appropriate permittivity in GHz range, its composite has been widely used as radar wave absorber with high performance. In this work, the flakeshaped FeSiAl/paraffin composites with various volume concentration and thickness were prepared. Their electromagnetic parameters in 0 1~18 GHz were measured by VNA. Their radar wave reflection properties at the airabsorber interface and absorbermetal plate interface and the reflection loss properties were studied by measuring the S 11 coefficients with and without a terminated metal plate. According to the measured S 11  coefficients and the simulation data, the relationship between the frequency position of the reflection loss (RL) peak and the absorber thickness was confirmed directly, and furthermore, the intensity and bandwidth of the RL peak were investigated deeply from viewpoint of their origin on the base of interface reflection model.
