Abstract
This paper present the design, development and characterization of the hexagonal ferrite powder [BaCo/sub 0.5/spl delta//Ti/sub 0.5/spl delta//Mn/sub 0.1/Fe(11.87-/spl delta/)O/sub 19/] at /spl delta/=1.6 as microwave absorber. The hexagonal ferrite powder has been developed by dry attrition and sintering procedure. The developed ferrite powder 60% by weight has been mixed in epoxy resin to form a microwave absorbing paint. This paint was coated on conducting aluminum sheet to study absorption characteristics of linearly polarized TE wave at X band. The experimental and computed results for different coating thickness have been reported. It has been found that it shows the broadband characteristics with minimum absorption of 6.5 dB from 8 to 12 GHz for a coating thickness of 2 mm. These paints are very useful in military application such as RCS reduction, camouflaging of the target and prevention of EMI etc.
