Abstract
In this work, the spinal ferrite has been prepared. The prepared ferrite material was used as radar absorbing material ( ). The absorption for microwaves was investigated via the use of network analyzer method. The values of reflectivity and absorption were calculated as a function of frequency at -band with an (0.0225) increase. The relationship between reflectivity and absorption was plotted as a function of frequency for all prepared samples and their sintering temperature: (1050, 1100, 1150) 0C. The results were appearance of a numbers of resonance peaks at -band frequencies. Further, it was shown that the highest values of the absorption and less values of the reflectivity were reached at the sintering temperature 1150 0C. Also, testing of diffraction ( ) was made for this ferrite, where the results showed compatibility with standard results except for secondary phases with the ferrite samples.
