High resolution NMR spectrometry is possible in nonhomogeneous magnetic fields if the static and RF magnetic fields are perpendicular and correlated in the measurement volume. From the easy-axis rotation theorem and the Amperian currents model, it is possible to exactly match two magnetic fields in two-dimensional systems. We derive a basic probe element that fulfills these conditions. Then we present a portable NMR design. The static and RF magnetic fields of the probe are matched on a large volume.
