EaZE: Flexible Wideband Time-Delay Beamforming using Passive, 3D Reconfigurable, Wideband Metasurfaces
Enhanced acoustic zones that emphasize acoustic information in desired 3D spatial regions in a contactless manner, are integral to the vision of immersive spaces. Yet, realizing such zones in practice requires catering to wideband audio signals and 3D spatial selectivity in a cost-effective, deployment-friendly manner,...
