Temporal aiming with temporal metamaterials

Tailoring and manipulating electromagnetic wave propagation has been of great interest within the scientific community for many decades. In this context, wave propagation has been engineered by properly introducing spatial ...

New ultrafast camera takes 70 trillion pictures per second

Just about everyone has had the experience of blinking while having their picture taken. The camera clicks, your eyes shut, and by the time they open again, the photo is ruined. A new ultrafast camera developed at Caltech, ...

Scientists simulate a black hole in a water tank

Certain phenomena that occur in black holes but cannot be directly observed in astronomic investigations can be studied by means of a laboratory simulation. This is possible due to a peculiar analogy between processes that ...

Correcting the eyesight of microscopes

Scientists have discovered a new property of wave propagation that leads to a new way to improve the resolution of virtually all optical technologies, including microscope lenses, telecommunications, laser-based lithography, ...
