Now, a team led by Professor Sascha Feldmann at EPFL’s Laboratory for Energy Materials has developed a high-sensitivity, ...

EPFL scientists have developed a new technique that lets researchers watch, with unprecedented sensitivity, how materials ...

Centrosymmetric crystals have always absorbed equal amounts of left- and right-handed circularly polarized light—until now ...

Researchers have designed a metasurface that can be continuously tuned from linear to elliptical birefringence, opening up the entire space of polarization control with just one device. This ...

Figures 6(c) and 6(d) plot the diffraction efficiencies versus azimuth angles of the probe beam when the polarization gratings were written with the two coherent waves with orthogonal polarizations.

The largest radio telescope FAST detects 90% circular polarization and rapidly changing linear polarization in the bursts of a fast radio burst (FRB) repeater, imposing new constraint on radiative ...
