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, ...

Applying a saturated bias voltage facilitates LP wave to LHCP wave conversion. Unlike conventional fixed-response linear-to-circular polarization converters, our design presents a readily ...

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 ...

Enteroviruses (EVs), such as EV-D68, EV-A71, and CVB3, cause significant human disease; yet, no antivirals are currently approved. The highly conserved 2C protein, an essential AAA+ ATPase and ...

Transition metal-catalyzed C–N cross-coupling reactions are pivotal in synthesizing pharmaceuticals and agrochemicals. Nickel catalysts, while cost-effective, suffer from rapid deactivation via ...
