Abstract

Double-layer broadband absorber for Ku band of CaCu3Ti4O12 (CCTO), Carbonyl iron (CI) and MnZn Ferrite composites was studied. Based on combination of different composites and thicknesses, among the various combinations investigated the best result was observed for the structure formed by the junction of CI composite with 2 mm and MnZn ferrite composite with 3 mm. Reflection loss measurements showed that this double-layer absorbed more than 90% of EM wave within the 12,4 to 16,06 GHz frequency range.
