Understanding how light travels through various materials is essential for many fields, from medical imaging to manufacturing. However, due to their structure, materials often show directional ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could ...

To Newton's atomic theory of light, there was the very successful wave theory, which explained typical light behavior such as refraction (the change in the direction of propagation of light when ...

The researchers managed to image light propagation with a microscope and saw that it behaved as predicted. Moreover, they witnessed the topology, or mathematical description, in the observed light.

As shown in this artist's rendering, a light beam shining on a glass prism generates evanescent waves and spin-momentum locking, suggesting potential practical applications in photonic communications ...

The dark side of light: negative frequency photons The impact of something we thought couldn't exist has now been detected.

Researchers at the European Laboratory for Nonlinear Spectroscopy (LENS) have developed a novel experimental technique to better understand light propagation in materials with anisotropic ...
