Description

Stéphane Azar, Francisco Rodríguez-Fortuño, and Sebastian Golat calculated in 2025 how light reflects off a surface that slides sideways at constant speed. Textbook reflection formulas assume stillness. Using classical electrodynamics with relativity, they derived the reflection in the frequency-wavevector domain, valid from far field down to the near field's skin.

Motion mixes polarizations: reflected light gains a cross-polarized share, except when the slide runs inside the plane of incidence. Feeding a standard metal model into the formulas tilted the surface waves' dispersion, so plasmons prefer one direction and refuse the return trip. The authors offer the result as a rigorous base for nonreciprocal optics. Moving media, they show, can steer light without magnets.
