Aerodynamic and vibration damping skin for cylindrical structures
Unit cell of locally-resonant lattice tuned to damp noise source.
Invention Summary:
During rocket launches and stage separations, intense vibrations and shock waves can damage sensitive payload electronics. Traditional isolation systems are often heavy and increase fuel consumption, making lightweight vibration-damping solutions essential....

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...
