Transparent gradient index lens for underwater sound based on phase advance
Theodore P. Martin, Christina J. Naify, Elizabeth A. Skerritt +6
Spatial gradients in refractive index have been used extensively in acoustic metamaterial applications to control wave propagation through phase delay. This study reports the desig…

Sonic Gradient Index Lens for Aqueous Applications
Theodore P. Martin, Michael Nicholas, Gregory J. Orris +3
We study the acoustic scattering properties of a phononic crystal designed to behave as a gradient index lens in water, both experimentally and theoretically. The gradient index le…
