Inverse Design Framework Achieves 0.142% Group-Velocity Variation in Pseudomagnetic Phononic Boundary States

The arXiv preprint demonstrates a surrogate-assisted inverse design method that precisely engineers boundary-state dispersion in pseudomagnetic phononic crystals for targeted group velocities. Verification shows extreme linearity or controlled slowing within narrow bandwidths. This bridges topological waveguiding to practical acoustic control applications.

Next steps involve integrating these designs into 3D-printed or MEMS-scale devices for lab testing, potentially enabling tunable slow-wave phononic components by mid-2027.
