Method to Achieve Total Acoustic Transmission between Water and Air
​ A plane wave is incident from the water side of the asymmetric panel. The plates are separated by ribs set a distance 𝑑 apart with the intermediate space assumed to be air. Invention Summary: Effective sound transmission between water and air is challenging due to the vastly different acoustic impedances. Current methods are limited as they...
