Researchers have introduced an innovative two-step excitation approach that makes it possible to efficiently generate and clearly separate different modes of hyperbolic polaritons. An international co ...

A new diagnostic method has been created, based on Birefringence, the ability of substances to change the polarization state of light. With this method, doctors around the world can easily, rapidly ...

Scientists have developed an ingenious method to create and control ultra-confined light waves, a significant step towards ...

Scientists explore the physics of how polarization-filtered colors emerge, how they can be controlled, and why subtle changes in viewing angle, sample orientation, and the order of layers of films ...

Glass is everywhere. Whether someone is gazing out a window or scrolling through a smartphone, odds are that there is a layer of glass between them and whatever it is they're looking at. Despite being ...

According to quantum electrodynamics (QED) - a quantum theory that describes how light and matter interact - it’s predicted that space is actually full of 'virtual particles' that pop in and out of ...

ETH researchers led by Raffaele Mezzenga have developed a new diagnostic method. It is based on Birefringence, the ability of substances to change the polarisation state of light. With this method, ...

This news release is available in German. Nothing could be simpler: a drop of blood is placed on a special carrier substance; after a wait of a few minutes, the slide is placed on a device that emits ...
