Study of the Effect Ratio Mixture for Active Material on the Frequency Response Curve for RAM Material

Frequency response curves in the microwave band (8-12.4)GHz of absorbing materials (RAM) involving (FerriteIron) with Epoxy and Hardener mixtures are studied. The aim is to provide experimental data of the effect of the mixing ratio on both the frequency at which the maximum absorption takes place and the band width, the standing wave equipment SWR is used in this work, it is found that both maximum absorption frequency [f(max)] and band width tend to increase with increasing ferrite ratio and decrease iron ratio in the mixture.
