The resulting IC uses surface acoustic waves and can image objects more than 100 feet away. We would imagine this could be helpful for other applications like 3D scanning, too. The system weighs ...

One way around this problem lies in the interaction between two types of waves: those on the ocean’s surface, and those that reside underwater. My research group has just published a paper ...

S-waves which oscillate up and down, perpendicular to the direction of travel; and surface waves, which travel along the surface of Mars similar to ripples in a pond. The new research was focused ...
