| Abstract: | In this paper the experimental result of microwave absorber with a single layer coating of ferrite and silicon carbide (SiC) based paint for X-band is presented. Samples of M-type hexagonal ferrite powder [Ba(MnTi)18Fe8.4O19] has been developed by dry attrition and sintering process. These developed ferrite powder and SiC powder have been mixed in epoxy resins to form a microwave absorbing paint. This paint was coated on aluminum sheet for absorption studies. The frequency selective surface (FSS) patterns are embedded on the surface of absorber sheet and tested experimentally at X-Band. It was found that SiC based microwave absorbing paint provide wide band absorption characteristics with minimum absorption of 10 dB from 9.5 to 12 GHz for a coating thickness of 1.84 mm. |
