An RF resonator designed for strong and fast driving of nuclear spins with applications in quantum sensing and microscopy. The resonator is a spiral structure composed of two metallic layers separated by an insulating material. It achieves high Rabi frequencies, constrained only by thermal dissipation, while maintaining compatibility with advanced technologies like quantum sensing, confocal fluorescence microscopy, atomic force microscopy, cryogenic temperatures, and ultra-high vacuum environments.
