Ferrite phase of BaFe9(MnCo)1.5Ti1.5O19 as anti-radar coating material

In surveillance mission, a technology to camouflage military vehicle and weaponry is required for avoiding the detection by enemy´s radar, for example by coating them using Radar Absorbing Material (RAM). RAM is a class of material that can absorb electromagnetic signal at a certain frequency range. In this paper nanostructure engineering of ferrite material has been synthesized using ferrite phase alloy of BaFe₉MnxCoyTi_1.5O₁₉ to reduce radar electromagnetic wave. The material was syntesized using sol-gel method. The measurements were done by using X-Ray diffraction (XRD), B-H analyzer, and waveguide to know its structure, magnetic characteristic, and electromagnetic absorption, respectively. The XRD measurement, showed that the ferrite phase of BaFe₉MnxCoyTi_1.5O₁₉ has identical structure with pure BaFe₁₂O₁₉. The B-H analyzer showed that the coercivity of BaFe₉MnxCoyTiz_1.5O₁₉ did not change for certain number of × and y. While from the electromagnetic absorption measurement showed that BaFe₉(MnCo)_1.5Ti_1.5O₁₉ has the highest electromagnetic absorption at X-Band frequency range.
