| Abstract | ||
| In this research, samples of spinel ferrite of the form Mg0.2 Zn0.8 Fe2O4 has been prepared by the method of solid state reaction (ceramic method ) for absorbing spectrum of X- Band waves with the range of frequencies ( 8-12 ) GHz and study its characteristics using the waveguide device. The values of reflection coefficient, absorption coefficient and attenuation coefficient were calculated for all (3) prepared samples and their sintering temperature ( 1100, 1150, 1200 ) °C. The results were appearance of a number of resonance peaks at x-band frequencies. Further, it was shown that the less values of the reflectivity and highest values of the absorption and attenuation were reached at 1200°C. The results of x-ray diffraction ( XRD ) showed compatibility with standard results except for some secondary phases with the ferrite samples.
