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...

An Underwater Acoustic Lens
Invention Summary: Sending and receiving information below the water surface is important but challenging. Techniques such as Sonar use acoustic waves in water to transmit information. Acoustic metamaterials enable Sonar devices to control, direct and manipulate sound waves for increased functionality and higher efficiency. Specifically, acoustic...
