Characteristics of electromagnetic radiation absorption in plain coverings with ferrite Mg-Mn

The production technology of covering electromagnetic radiation absorbers of the blanket type is related with the development of new materials and its electromagnetic properties. In this paper it is presented a methodology of one layer plain covering production, with absorption characteristics tuned in the frequency of 9 GHz. These coverings have been confectioned joining ferrite powder of Mg-Mn with aliphatic resin with base epoxy. Reflectivity measurements have been carried out in three samples with different compositions, in the 8 to 12 GHz frequency range, to study its electromagnetic radiation absorption characteristics. The reflectivity data are presented and compared between the different samples.
