A novel kind of circular polarization and dual-frequency linear polarization microstrip antennas is proposed. The designs are based on the anisotropic property of the complementary split ring ...

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

Unlike conventional fixed-response linear-to-circular polarization converters, our design presents a readily implementable approach for reconfigurable polarization conversion, holding significant ...

Scientists have discovered a centrosymmetric crystal that behaves as though it is chiral – absorbing left- and right-handed ...

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

A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities. The ...

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

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 ...

Circular polarization is less susceptible to signal fading since the polarization most easily propagated is achieved whatever the intervening propagation environment might happen to be. In ham radio, ...

Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or ...
