Abstract: Research on metamaterials has evolved to include engineering adjustable, rather than fixed, properties. Shunted piezoelectric materials have previously been used to to tune elastic waves propagating in beams and plates, and in this work the authors incorporate them into tunable resonators in a lattice structure. This cellular lattice exhibits highly directional yet symmetric pathways for energy propagation at specific frequencies, but the real draw here is tuning subsets of resonators to alter the symmetry. This can override any inherent lattice pathway, and thus allows the tailoring of material properties for electromechanical control of vibrations.
