Effects of dispersion and absorption on Anderson localization in randomly layered metamaterials have being studied analytically and numerically. It is shown that the radiation in one-dimensional disordered systems can be delocalized in $\mu $ or $\varepsilon $-near-zero disordered media - a new
form of delocalization that occurs in one dimension. We have also demonstrated disspersion-induced suppression of Anderson localization in mixed stacks with either dielectric permittivity or magnetic permeability disorder. However, the presence of both forms of disorder enhances localization.
