A strong-coupled magnon polaritons is essential for the applications in effective quantum information transfer. In our previous work, the numerical calculations of a magnetic chiral meta-molecule composed of a copper helix structure and a ferrite rod showed an ultra-strong coupling between magnons and photons. In this study, the microwaves transmission properties of the meta-molecules with an external magnetic field were experimentally observed, which revealed ultra-strong coupling of the magnons in the ferrite and the photons through the helix structure.
