In order to avoid forming an electrical conductive network due to surface connections, the magnetic metal fibers were coated with SiO2 for surface modification by the sol-gel process. The microstructure, composition and electromagnetic characteristics of SiO2 -coated and uncoated metal fibers were studied using SEM, EDAX, and a voter network analyzer. The reflectivity was simulated using the RAMCAD software. The electromagnetic parameters and absorption properties of SiO2-coated metal fibers were improved greatly due to optimal impendence matching and the electric conductivity decreased, compared to those of uncoated materials.
