Zusammenfassung:All‐Oxide Metasurfaces In article number 2401064 by Stuart S. P. Parkin and co‐workers, a novel method for forming planar metasurfaces using ionic liquid gated nano‐regions within a continuous oxide thin film is demonstrated. The cover shows an example of arrays of metallic antennae (the metallic perovskite SrCoO3‐δ) created within insulating brownmillerite SrCoO2.5. Anomalous reflection of light is exhibited.
