Machine Learning Driven Inverse Design of Broadband Acoustic Superscattering

Advanced Intelligent Discovery, Volume 2, Issue 5, October 2026.
Multilayer acoustic superscatterers are designed using machine learning to achieve broadband superscattering and strong sound insulation. By incorporating a weighted mean absolute error into the loss function, the forward and inverse neural networks accurately map structural parameters to spectral responses.

Navigating Competing Constraints in Acoustic Metamaterials via Physically Admissible Design Spaces

Small Structures, Volume 7, Issue 10, October 2026.
A physics‐informed variational autoencoder is developed for inverse design of multilayer Helmholtz‐resonator acoustic metamaterials. By embedding an analytical acoustic model within the generative framework, physically admissible latent design spaces are learned, enabling efficient Bayesian optimization under competing requirements of high absorption ...
