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 ...
