1. A radio-frequency (RF)-resonator for resonant transmission and reception of RF-signals at a desired resonance frequency into and out of a sample in an investigational volume within a homogeneous magnetic field B0 of a nuclear magnetic resonance(NMR)-apparatus, the RF-resonator comprising:

  • at least two spatially separated superconducting components; and

    normally conducting connection elements coupling together said superconducting components, wherein said superconducting components do not form, either individually or collectively, a closed resonance system capable of resonating at the desired resonance frequency, and said superconducting components, together with said normally connecting elements, form at least one closed resonance system capable of resonating at the desired resonance frequency.
