Acoustic metamaterial can send complex signals directly between water and air

Researchers from IMDEA Materials Institute, in collaboration with China's Nanjing and Huazhong Universities, have developed a new acoustic metamaterial capable of transmitting complex sound signals directly between water and air. The advance, reported in the paper "High-dimensional multiplexed metamaterial for cross-media all-sound communication," introduces a novel approach that could significantly improve underwater communication technologies and enable new applications ranging from ocean monitoring to medical imaging.
