Temporal evolution of indirectly coupled resonators in open systems
Long-range signal propagation is essential for modern communication and quantum technologies, yet it induces travelling wave mediated indirect coupling between distant resonators. This effect is often obscured in steady-state transmission due to interference. Here, the authors demonstrate this information concealment and reveal the hidden coupling in a meter-separated cavity magnon--polariton system. The coupling is observed in time-domain transient measurements, independently confirmed by frequency-domain steady-state absorption. The underlying mechanism is further validated using coupled LRC circuits, providing a unified understanding across platforms.
