This paper presents the utilization of planar resonator to generate magnon mode in a Yttrium Iron Garnet (YIG) and photon mode in a ring resonator. A simple configuration using YIG-loaded planar resonator is proposed for investigating interaction between the modes and accessing coupling of magnon-polariton. Those modes were found from S-parameter by applying external magnetic fields bias upon the configuration. There were two magnon modes at the frequency of 3.692 GHz and 5.788 GHz, and three photon modes at the frequency of 1.974 GHz, 4.151 GHz and 5.788 GHz. Based on simulated results verified by experimentation, there was a significant shift of resonant frequency on the configuration to higher frequency, in which it is mostly affected by the interaction between magnon and photon modes. In addition, this work will also pave the ways for magnon and photon modes generation exploring a quasi-particle magnon-polariton.
