人工电磁材料等效磁导率的研究与计算

Study and Calculation of the Effective Permeability in a Meta-Material

本文研究了人工磁性材料的等效磁导率提取与计算问题。等效磁导率是指人工结构材料的电磁响应可以用等效的磁导率电磁响应来等效表示。在此处的等效主要是指散射参数的电磁响应等效。文中通过利用平均场的方法得到了等效的磁导率,平均场采用高斯面积分和体积分完成。由场平均方法得到的等效磁导率与散射参数反演得到的等效磁导率进行了比较,两种结果符合一致。

The calculation of the effective permeability in a meta-material were studied in this article. The "effective" in this article indicate the electromagnetic responsibility of the scattering parameters. The effective permeability is obtained by the field summation. The field summation is completed using the area and volume integral of Gauss. The result of the effective permeability is calculated both by the field summation and the scattering parameters and the results have a good agreement.
