摘要:
Based on the Maxwell equation, the electromagnetic model in the coaxial fiber was described. The interaction with electromagnetic wave was analysed and the theoretical formula of axial permeability (mu(parallel to)), axial permittivity (epsilon(parallel to)), radial permeability (mu(perpendicular to)) and radial permittivity (epsilon(perpendicular to)) of Fe-C coaxial fiber were derived, and the demagnetization factor (N) of fibrous material was revised. Calculation results indicate that the composite fiber has stronger anisotropy and better EM dissipation performance than the hollow carbon fi...
