Magnetic Field induced control and Multiple Magnomechanically Induced Transparency in Single Cavity

Abstract

We investigate magnomechanically induced transparency (MMIT) in a microwave 3D copper cavity with two YIG spheres under varying interaction parameters. Numerical simulations show that the steady-state magnon number increases with stronger coupling between cavity photons and magnons, and is sensitive to both bias and drive magnetic fields. Pronounced peaks in the magnon population near resonant fields highlight the importance of the bias field in energy transfer. The transparency windows are tunable, with up to quadruple windows depending on the coupling and magnon-phonon interactions, as seen in the transmission spectrum. Dispersion analysis reveals normal and anomalous regions, enabling slow and fast light propagation modulated by coupling strength. Phase and group delay variations, influenced by the drive field, further validate the tunability of transparency windows. This study demonstrates the potential of MMIT for precise control with out any additional non-linearity over light-matter interactions, with applications in quantum information processing and optical communications.
