Abstract EN

In this work, Microwave absorbing coatings were prepared in the X-band region, in a form of three layers of ferrite powder (MnFe2O4), iron powder and manganese oxide powder (MnO2) with (1)mm thickness for each layer.

A study of layer exchange effect on absorption, when exposed to direct radiation was conducted.

In this case, a standing wave ratio SWR system was used in which it was found that when the three layer coating (3mm thickness) were exposed to direct microwave radiation, a greater absorption values were obtained (86 %).

Hence, an exchange of coating layers does have a good impact on absorption values at specific frequencies.
