The evolution of acoustic metamaterials, from static to dynamic designs

Chiara Daraio, California Institute of Technology

Phononic crystals and acoustic metamaterials are materials with a tailored, architected structure, designed to achieve properties that depart from those found in natural or more “conventional” engineering materials. Initial realizations of these materials were periodic and derived their properties from an interplay of the constitutive material responses and the architected geometry. More recently, developments in the field of metamaterials focused on the effects of disorder, nonlinearities and tunability. This increasing complexity allows material designers to control more precisely wave propagation and harvest the richness of nonlinear phenomena. Current trends in phononics suggest a growing interest in the creation of metamaterials with programmable responses and metamaterials with autonomously adapting morphology. In this talk, I will highlight some of our recent work in programmable, nonlinear metamaterials and their possible application to engineering problems.
