  Developing hybrid materials and structures for electromagnetic wave
engineering has been a promising route towards novel functionalities and
tunabilities in many modern applications and perspectives in new quantum
technologies. Despite its established success in engineering optical light and
terahertz waves, the implementation of meta-resonators operating at the
microwave band is still emerging, especially those that allow for on-chip
integration and size miniaturization, which has turned out crucial to
developing hybrid quantum systems at the microwave band. In this work, we
present a microwave meta-resonator consisting of split-ring and and spiral
resonators, and implement it to the investigation of photon-magnon coupling for
hybrid magnonic applications. We observe broadened bandwidth to the split ring
modes augmented by the additional spiral resonator, and, by coupling the modes
to a magnetic sample, the resultant photon-magnon coupling can be significantly
enhanced to more than ten-fold. Our work suggests that combinatorial, hybrid
microwave resonators may be a promising approach towards future development and
implementation of photon-magnon coupling in hybrid magnonic systems.
