This study presents a planar hybrid system consisting of an electric-field-coupled resonator (ELCR) and yttrium iron garnet (YIG) film, designed to investigate the interaction between photons magnons at room temperature. has been simulated using commercial electromagnetic full-wave simulator CST Microwave Studio. The phenomenon anti-crossing photon mode ELCR magnon modes YIG was observed by analyzing |S21|-versus-frequency spectrum under varying strengths bias magnetic fields. We present comprehensive theoretical framework that explains effect resulting from photon-magnon coupling (PMC) provide estimations for strength PMC (Δ). Additionally, manipulated through two distinct methods: adjusting thickness (tYIG) film positioning films along microstripline. For (for tYIG = 25 μm), Δ comes 58 MHz, while changing 2 μm 50 μm, enabling more precise control parameter across span 17 MHz 84 MHz. Similarly, different location microstripline allowed manipulation 5 resultant can be significantly tuned 400% 900% in planar-geometry ELCR-YIG system. research offers avenues developing innovative systems afford greater over magnitude configuration, representing promising direction future advancements magnonic systems.
