摘要： RF electric fields produced by electric potential differences in the NMR probe coil windings may penetrate the NMR sample and sample tube causing sensitivity loss and increased noise in NMR spectroscopy. Electrically conducting strips in close proximity to the windings of the NMR probe coil and oriented at right angles to direction of the coil winding they cross provide an alternative path for these electric fields while causing negligible effect upon the RF magnetic field, thereby increasing the sensitivity of the NMR probe.

摘要： A radio-frequency (RF) resonator system, in particular, for a magnetic resonance (MR) probe, comprising at least one RF resonator with a substrate, on which a conductive structure is applied, wherein the conductive structure comprises regions of capacitive and inductive elements, is characterized in that the conductive structure is coated at least in the regions of the capacitive elements with at least one dielectric layer that covers the regions of the capacitive elements at least partially, wherein the local thickness of at least one of the dielectric layers is set in dependence on the resonance frequency of the uncoated RF resonator, on a defined resonance frequency of the resonator once it is coated, on the dielectric constant of the substrate and on the dielectric constant of the materials of the dielectric layers. The inventive resonator system can be set to the required resonance frequency quickly, at low cost, reversibly, and with high precision and at the same time the dielectric strength of the resonator system is increased.
