Abstract
The complex permeability (μr*) and permittivity (εr*) of radar absorbing materials (RAMs) play a key role in determining the reflection or attenuation properties of the incident microwave. The real (μ' and ε') and imaginary components (μ'' and ε'') of μr* and εr* in the frequency range 8-16 GHz, and their relationship with microwave absorbing properties, have been investigated for doped M-type barium hexaferrites in polychloroprene (CR) matrices. The individual and simultaneous substitutions of Fe3+ ions by Co2+, Ti4+ and Mn3+ and of Ba2+ ions by La3+ and Na1+ make possible the use of these materials as RAMs, based on the hexaferrite`s μr* frequency dependency, responsible for the location of its natural resonance. The double substitution of Ba2+ and Fe3+ (LaNaCoTiMn-BaHF) resulted in the best microwave absorption (99.9 %) for the frequency of 15 GHz.
