We have analyzed numerically the localization length of light $\xi$ for nearly periodic arrangements of homogeneous stacks (formed exclusively by right-handed materials) and mixed stacks (with alternating right and left-handed metamaterials). Layers with index of refraction $n_1$ and thickness $L_1$ alternate with layers of index of refraction $n_2$ and thickness $L_2$. Positional disorder has been considered by shifting randomly the positions of the layer boundaries with respect to periodic… 

Non-conventional Anderson localization in a matched quarter stack with metamaterials

We study the problem of non-conventional Anderson localization emerging in bilayer periodic-on-average structures with alternating layers of materials, with positive and negative refraction indices

Faraday and Kerr Effects in Right and Left-Handed Films and Layered Materials

Abstract In the present work, we study the rotations of the polarization of light propagating in right and left-handed films and layered structures. Through the use of complex values representing the

Band Structure Analysis of SH Wave Propagating in Nanoscale Layered Metamaterial Structures

This study is devoted to the analysis of the band structures of the anti-plane transverse wave (SH wave) in nanoscale layered metamaterial structures. Attention is restricted to normal incidence of

Resonant enhancement of Anderson localization: analytical approach.

TLDR
It is shown that the analytical expressions obtained by standard methods for continuous random potentials can be used in the discrete model, in spite of the presence of resonances that cannot be described by conventional theories.

Wave attenuation and trapping in 3D printed cantilever-in-mass metamaterials with spatially correlated variability

TLDR
It is demonstrated that the vibration attenuation profile is strictly related to the spatial profile of the variability, and that there exists an optimal disorder degree below which the attenuation bandwidth widens; for high disorder levels, the band gap mistuning annihilates the overall attenuation.

Complex Faraday and Kerr Rotations in Right and Left Handed Films

By studying the rotations of the polarization of light propagating in right and left handed films, with emphasis on the transmission (Faraday effect) and reflec- tions (Kerr effect) of light and

Disordered mixed transmission lines: localization behavior

Abstract.We introduce a new type of transmission line: the mixed transmission line. This system is formed by the repetition of a set of p successive direct cells followed by q successive dual cells.

TLDR
The frequency dependence of the localization length l for acoustic and electromagnetic waves in a one-dimensional randomly layered medium is studied both numerically and analytically and the dependence of this minimum localization length on the amount of randomness is presented.

We study wave propagation in mixed, 1D disordered stacks of alternating right- and left-handed layers and reveal that the introduction of metamaterials substantially suppresses Anderson localization.

TLDR
This work investigates the properties of stratified one-dimensional disordered media, in which all layers have the same thickness, but the refractive indices have a random component, and finds that the localization length exhibits a surprisingly rich behavior at these wavelengths.
