Metasurface opens world of polarization
Polarization, the direction in which light vibrates, is invisible to the human eye. Yet, so much of our optical world relies on the control and manipulation of this hidden quality of light.

A team of researchers from Germany, the Netherlands and Italy has developed a way to use scattered light to map nerve fiber pathway crossing points in the brain. In their paper published in the journal Physical Review Letters, ...
A team of researchers from Russia and Greece reports a way to determine the origins and nature of quasar light by its polarization. The new approach is analogous to the way cinema glasses produce a 3-D image by feeding each ...
