Non-Local Phononic Crystals for Dispersion Customization and Undulation-point Dynamics
Arash Kazemi, Kshiteej J. Deshmukh, Fei Chen +4
Dispersion relations govern wave behaviors, and tailoring them is a grand challenge in wave manipulation. We demonstrate inverse design of phononic dispersion using non-local inter…
Rolling Waves with Non-Paraxial Phonon Spins
Peng Zhang, Christian Kern, Sijie Sun +2
We demonstrate a new class of elastic waves in the bulk: When longitudinal and transverse components propagate at the same speed, rolling waves with a spin that is not parallel to…
Harnessing Geometric Frustration to Form Band Gaps in Acoustic Channel Lattices
Pai Wang, Yue Zheng, Matheus C. Fernandes +6
We demonstrate both numerically and experimentally that geometric frustration in two-dimensional periodic acoustic networks consisting of arrays of narrow air channels can be harne…
Topological Phononic Crystals with One-Way Elastic Edge Waves
Pai Wang, Ling Lu, Katia Bertoldi
We report a new type of phononic crystals with topologically non-trivial bandgaps for both longitudinal and transverse polarizations, resulting in protected one-way elastic edge wa…
