Abstract
Increased distributed capacitance for an NMR resonant probe coil is obtained by a surrounding conducting surface which is congruent to and spaced from the major portion of the RF current density distribution on the surface of the inductive component of the resonator. This surface is interrupted with one or more gaps to avoid or control circulating currents on the conducting surface which reflect the circulating currents of the inductive component.
