By measuring fracton mode displacements in artificial piezoelectric composities with hierarchical structure, we find direct evidence of their localized and self-similar character. Clear indications of the existence of multiple fracton and phonon regimes are also presented.

Abstract
By measuring fracton mode displacements in artificial piezoelectric composities with hierarchical structure, we find direct evidence of their localized and self-similar character. Clear indications of the existence of multiple fracton and phonon regimes are also presented.
