Abstract
We investigate the interaction between microwave photons and magnons in a system of two magnetic spheres within a microwave cavity, subjected to time-periodic driving fields. Through Floquet engineering, we demonstrate on-demand control over the cavity-magnon coupled dynamics, enabling tunable nonlocal magnon-magnon coupling mediated by the cavity mode. This approach facilitates reversible bright-dark mode conversion, overcoming the limitations of static coupling schemes and paving the way for coherent control of diverse systems within microwave cavities.
