Using super-structures one can effectively change these “constants”. In this way we obtain functionalities such as wave-guiding\, acoustic lensing or programmable failure. I will show how topological band theory\, known from the description of electrons in solids\, provides us with a powerful design-principle for such mechanical metamaterials. Moreover\, mechanical metamaterials offer a powerful platform for the study of fundamentally new phenomena that are hard to observe in other arenas. Here\, I will highlight the first measurement of a quadrupole topological insulator in a silicon based metamaterial\, the implementation of an axial gauge field in an acoustic Weyl system and the measurements of fragile topology.
