The super wideband electromagnetic wave absorber in RF-A-PF type has been proposed, which can be used for an anechoic chamber, wall material to prevent TV ghost, etc, In this paper, Nix-Mg0.1-Zn(1-x-0.1)·Fe2O4 Ferrite Powder has been fabricated. Using this, then, [Nix-Mg0.1-Zn(1-x-0.1)·Fe2O4-Rubber composite for RF-layer in the RF-A-PF type absorber has been fabricated and its characteristics has been analyzed. As a result, it has been shown that the Nix-Mg0.1-Zn(1-x-0.1)·Fe2O4-Rubber composit with the quantity x of Nix between 0.5 and 0.6 is suitable for the RF-layer in the case of which the grain size is sub-micrometer order.
