Wave propagation phenomena in architected (meta)materials and phononic crystals is an active and growing research area. The ability of engineering materials with targeted stop band frequencies, anomalous refractive behavior, negative stiffness/mass offers great research and technological perspectives with a large variety of engineering applications. Moreover, these materials can be designed to possess tunability and adaptivity through various mechanisms, such as multiphysics coupling with external fields, large deformations, and elastic instabilities. This mini-symposium will address recent computational, theoretical and experimental advances in the research area of wave propagation in engineered (meta)materials and phononic crystals. Topics of particular interest include:

• Architecture materials and phononic crystals for band-gap formation

• Wave propagation in soft materials, and soft phononic crystals

• Topological optimization of acoustic-elastic metamaterials and phononic crystals

• Multiphysics phenomena in phononic crystals and acoustic-elastic metamaterials

• Homogenization approaches for acoustic-elastic metamaterials

• Buckling induced switchable metamaterials and phononic crystals
