One-Way Absorption and Isolation in Space-Time-Periodic Superconducting Metasurfaces

Superconductors offer zero electrical resistance below a critical temperature, enabling advancements in various fields, from quantum computing and MRI to energy systems. This paper introduces a groundbreaking approach utilizing space-time-modulated superconductors for one-way absorption and isolation, marking a significant leap in metasurface technology. We explore the unique characteristics, analytical methods, and properties of these superconducting metasurfaces, demonstrating their capabilities in manipulating electromagnetic waves. Our findings highlight the potential of spatiotemporal superconducting surfaces in enhancing quantum computing, communication systems, and beyond. This research not only paves the way for novel applications of superconductors but also opens up new avenues in the design and development of advanced metasurfaces for wavecrafting.
