Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials
This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

Angle‐ and Polarization‐Tolerant Metasurface Designs Based on the Aperiodic Tiling
A novel aperiodic metasurface design is introduced to mitigate the inherent angle and polarization sensitivity of conventional metasurfaces. By employing a recently discovered aperiodic tiling approach, identical elliptical scatterers are arranged with systematic variations in their spacing and orientation, effectively minimizing spectral reflectance ...
