Many chiral devices emitting and detecting circularly polarized light require integration with highly reflective mirrors. Here we study advanced designs of chiral metacavities and suggest the strategies to achieve strong chiral optical response in the reflection geometry by combining mirrors and planar achiral metasurfaces.enTechnology::600: TechnologyConference Paper10.1109/Metamaterials65622.2025.11174163Conference Paper
