Metamaterials have been a hot topic in the acoustics community since the late 1990s, but there's no  consensus among researchers as to what a metamaterial actually is or when they first came about. Christina Naify (University of Texas - Austin) took a deep dive into the literature about metamaterials and then posed the question to an audience of researchers in a session at the ASA conference in Chicago. In this episode, we talk to her about what came up during this discussion.
