Light Behaves Differently in Newly Created Time Crystal

Scientists have created a new kind of photonic time crystal that can neaten and amplify electromagnetic waves, which could have potential applications in wireless communication systems, laser development, and electronic circuits. The crystal is made of ultra-thin sheets of artificial materials known as metasurfaces, which makes it easier to produce and examine photonic time crystals. The discovery of electromagnetic wave amplification along surfaces could improve integrated circuits and wireless communications.
