| Abstract: | The effect of Mg2+, Co2+and Ti4+ substitution on microwave absorption has been studied for BaMg0.5Co0.5Ti1.0Fe10O19 ferrite-acrylic resin composite in frequency range from 13 to 20 GHz. X-ray diffraction (XRD), scanning electron microscopy (SEM), vector network analysis and vibrating sample magnetometry (VSM) were employed to analyze structure, electromagnetic and microwave absorption properties of prepared ferrite. The obtained results of reflectivity demonstrate that by varying matching thickness along with weight percentage of ferrite to acrylic resin, the bandwidth coupled with reflection loss values of prepared composites can be easily tuned. Based on microwave measurement on reflectivity, it is found that BaMg0.5Co0.5Ti1.0Fe10O19 is a good candidate for wideband electromagnetic compatibility and other practical applications at high frequency. |
