Episode 10: Photonic time crystal amplifies electromagnetic signal

MRS Bulletin Materials News Podcast · Aug 8, 2023 · 4m

In this podcast episode, MRS Bulletin’s Sophia Chen interviews Xuchen Wang of Karlsruhe Institute of Technology in Germany about his work on photonic time crystals. While conventional crystals are composed of repeating unit cells in space, such as eight carbon atoms arranged in a cube to form a diamond, a photonic time crystal has a structure that repeats in time. Theoretical predictions of photonic time crystals referred to designs consisting of three-dimensional metamaterials whose properties are difficult to manipulate in the laboratory. Wang and his collaborators have adapted the…
