Extension of the Multipole Approach to Random Metamaterials

Figure 13

Effective material parameters for metamaterials exhibiting positional disorder along the lateral direction (𝑥-direction) governed by the Gaussian distribution function (Figure 11(b)). The first column gives the material parameters for a metamaterial ensemble having a mean period of 𝑧_𝑛=1.2, while the second column is for metamaterials having a mean period of 𝑧_𝑛=1.8.
