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

摘要

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 BaFeMnxCoyTiO 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 BaFeMnxCoyTiO has identical structure with pure BaFeO. The B-H analyzer showed that the coercivity of BaFeMnxCoyTizO did not change for certain number of × and y. While from the electromagnetic absorption measurement showed that BaFe(MnCo)TiO has the highest electromagnetic absorption at X-Band frequency range.
