Conical refraction, which is quite well-known in electromagnetic waves, has not been explored well in elastic waves due to the lack of proper natural elastic media. Here, we propose and design a ...

Add Yahoo as a preferred source to see more of our stories on Google. There are many glorious science-based terms when it comes to surfing. We all talk about swells, of course, the underwater energy ...

Results are presented for real-time seismic imaging of subsurface fluid flow by parsimonious refraction and surface-wave interferometry. Each subsurface velocity image inverted from time-lapse seismic ...
