Abstract

The use of absorbent materials is one of the most common ways to prevent radar visibility. In this study, considering the application of radar  absorbing materials, two important materials, one with high dielectric coefficient  and other with high permeability coefficient, (Perovskite Ba0.7Sr0.3TiO3 and ferrite Mn0.5Zn0.5Fe2O4),  being  good candidate for radar-absorbing materials, have been synthesized with a specific stoichiometry  by sol-gel method and were characterized by X-ray diffraction and scanning electron microscopy. In order to determine the radar absorption rate, five different nanopowder was prepared and the pigment was prepared with an 828 Epoxy resin and placed on a non-adsorbent surface with an approximate thickness of 1  mm and the amount of radar absorption by using the network analyzer in the 8-12 GHz range has been investigated. The results showed that the absorption of waves in the 8-12 GHz range is dependent to the dielectric coefficient and the material with a high permeability coefficient does not have any influence in the absorption. The highest absorb ion rate was observed for a material with high dielectric coefficient  of -24dB at about 9.5 GHz.
