Extension of the Multipole Approach to Random Metamaterials

Figure 12

Effective material parameters for metamaterials exhibiting positional disorder along the lateral direction (𝑦 direction) governed by the rectangular distribution function (Figure 11(a)). 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.
