Effective Electromagnetic Parameters of Stratified Polycrystalline Iron Fibers Absorbing Material

层状多晶铁纤维吸波材料中铁纤维分层取向规则排列，吸波材料表现为宏观各向异性。该文在长波长近似下，在计及多晶铁纤维电磁参数的各向异性及多晶铁纤维之间强相互作用的基础上，建立了层状多晶铁纤维吸波材料等效电磁参数理论模型，导出了等效电磁参数εｅｆｆ和μｅｆｆ的计算公式。由该文的理论可导出著名的ＱＣＡ－ＣＰ公式。

With regularly oriented iron fibers,stratified polycrystalline iron fibers absorbing material shows macroscopic electromagnetic anisotropy.Based on long wavelength approximation and in consideration of electromagnetic anisotropy of polycrystalline iron fibers and strong coupling interactions among polycrystalline iron fibers,the effective electromagnetic parameters theory of stratified polycrystalline iron fibers absorbing material is established,and the calculating formulas of ε eff and μ eff are derived.From the theory established in this paper,the well known QCA CP formula can be derived.
