【Abstract】 Based on the Maxwell Equation, the theoretical formulas of microwave complex permeability and permittivity of polycrystalline ironfiber absorbers are derived. The numerical calculations of polycrystatlline iron fibers around 5GHz have been carried out, and then the offects of diameter, aspect ratio and electrical conductivity on their electromagnetic parameters are discussed.更多还原
