Hexaferrite contribution to microwave absorbers characteristics

The influence is studied of Co-Ti substituted Ba hexaferrite on the efficiency of the hexaferrite-magnetite-graphite triple absorbing system of fillers dispersed in a rubber matrix. Using the planned experiment technique, the optimal ratio is determined of its components, as well as their influence on the absorber´s optimal thickness. The introduction of a hexaferrite in the system improves the composite absorbing properties manifested mostly in broadening the maximal absorption frequency band. It is assumed that the presence of the hexaferrite results in improving the long-range order of the absorbing fillers arrangement in the polymer matrix
