N2 - Double layer coating with variations in layer thickness on radar absorbent material (RAM), and Polyaniline doped by DBSA as a dielectric material has been successfully synthesized. Barium M-Hexaferrite doped by Zn2+ at x=0.9 as magnetic material has been also successfully synthesized. Polyaniline has been synthesized by polymerization method and Barium M-Hexaferrite has been synthesized by solid state method. Characterization results obtained the conductivity of Polyaniline and Barium M-Hexaferrite respectively 4.4 × 10-1 S/m and 2.09 × 10-3 S/m, which are in the range of conductivity values of semiconductor materials. The presence of Zn2+ doping successfully reduced hard magnetic properties of Barium M-Hexaferrite to be soft magnetic, with coercivity field (Hc) equals 0.0181 Tesla. Our current result represent that double layer design with variations PANi: PANi + BaM (3:1) has maximum reflection loss value about-29,6003 dB and 96.69% of energy absorbed. Whereas in variation of PANi: PANi + BaM (3: 1) has minimum reflection loss value about-15.2937 dB and 82.21% of energy absorbed. In addition, the coating thickness variations also affect the absorption band width, with the most effective absorption peaks in “D” variation with bandwidth equals 1.81 GHz in range of frequency 8 to 9.81 GHz.
