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.
