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

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

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

This paper shows a design method and its verification of a kind of linear-to-circular polarization converter, which allows for high-efficiency polarization conversion with good impedance matching and ...

A dual-band polarizer is presented that converts linear polarization into circular polarization with orthogonal handedness in the satcom bands 19.7–20.2 GHz and 29.5–30 GHz. The polarizer consists of ...
