Navigating Competing Constraints in Acoustic Metamaterials via Physically Admissible Design Spaces
Achieving simultaneously high absorption, broad bandwidth, and minimal thickness remains a central challenge in sound‐absorbing metamaterials. Multilayered Helmholtz resonators (MLHR) offer a promising route, yet effective design under competing constraints remains nontrivial. Here, we present MLHR acoustic metamateria...
