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

In this paper, we propose a dual-band reflective linear-to-circular (LTC) polarization converter based on metasurface. The metasurface element is consist of the ground, rectangular and symmetrical ...

This letter presents a reconfigurable polarization converter employing a metasurface with liquid crystals (LC) to convert linearly polarized (LP) waves into either left-hand circularly polarized (LHCP ...

Scientists have discovered a centrosymmetric crystal that behaves as though it is chiral – absorbing left- and right-handed circularly-polarized light differently. This counterintuitive finding, from ...

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