Extension of the Multipole Approach to Random Metamaterials
Figure 7
Effective material parameter curves for dipole ensembles exhibiting positional disorder. The effective permittivity and permeability curves for disordered dipole ensembles are presented for different values of disorder. The first column pertains to values obtained for a mean period of , while the second column pertains to those obtained for a mean period of . For the respective periodicities: (a) and (b) the positional disorder function; (c) and (d) the respective interseparation PDFs; (e) and (f) scaled real part of the permittivity; (g) and (h) scaled imaginary parts of the permittivity. Clearly, increase in disorder brings about a fall in the maximums of the response of the system.
