根据自由空间法介质材料介电常数测试原理,采用商用电磁场仿真软件给出了介质蜂窝材料等效复介电常数的分析方法,计算出了特定材料、格孔周期蜂窝材料的等效复介电常数。为验证方法的正确性,对等效介电常数的平板和相应的蜂窝的透射反射系数的幅度相位进行了比较,两者吻合良好。通过对宽带范围内蜂窝等效介电常数的计算表明,介质蜂窝具有微小的色散效应,随着频率增高,蜂窝的相对介电常数、损耗正切略微减小；蜂窝的磁介电常数接近为1,磁损耗正切接近为0。

According to the theory of adopting free space method to measure the dielectric permittivity, the commercial electromagnetic simulation software is used to analyze dielectric honeycomb effective complex permittivity. A certain material and geometry dielectric honeycomb effective complex permittivity is calculat-ed. The validity of the idea is demonstrated by comparing the simulation scatting matrix of the real honey-comb and effective dielectric panel board. Good agreement is achieved. The calculation of wide band dielec-tric honeycomb effective complex permittivity shows that the martial has a little dispersion property, the permit-tivity is increasing by frequency slowly and the mue is very close to 1,the magnetic tangent delta is close to 0.
