Strong Photon-magnon Coupling in a System of Two Coupled Resonators: Planar Photonic Crystal with Defect and Inverted Split-ring Resonator
We have numerically investigated the strong photon-magnon coupling in the system of two coupled resonators: planar photonic crystal with the defect and inverted split-ring resonator. The strong photon-magnon coupling $(g/2\pi=300 MHz$) with a spin-number-normalized coupling strength (single spin-photon coupling) was reached up to 0.535 Hz at the frequency of 5.1 GHz. The influence of the outer radius of the inverted spit-ring resonator on the coupling strength value is analyzed.
