根据强扰动理论,在长波长近似条件下推导出蜂窝结构吸波材料等效介电常数和等效磁导率的计算公式.电磁参数计算结果表明,蜂窝结构吸波材料等效介电常数和等效磁导率均小于吸收层的介电常数和磁导率,但等效介电常数的降幅更大,从而使等效介电常数更接近于等效磁导率,这正是吸波材料波阻抗匹配设计所需要的.反射率计算结果表明,不同的蜂窝高度,吸收层对应一最优厚度,使蜂窝结构吸波材料的反射率最低.这些结果对于蜂窝结构吸波材料设计具有一定的意义.
According to strong perturbation theory, the formula of equivalent dielectric constant and equivalent permeability of honeycomb structure absorbing material is deduced under the conditions of long wavelength approximation.The calculation results of electromagnetic parameters show that the equivalent permittivity of honeycomb structure absorbing material and Equivalent permeability are less than the dielectric constant and permeability of the absorption layer, but the equivalent dielectric constant decreases more so that the equivalent permittivity closer to the equivalent permeability, which is absorbing The results of reflectivity calculation show that the honeycomb structure has the lowest reflectivity of the honeycomb structure absorbing materials with different honeycomb height and absorption layer corresponding to an optimal thickness, Meaning.
