ABSTRACT:
A radio frequency volume resonator mounted on a generally cylindrical dielectric support can be operated in quadrature at one or more NMR frequencies. The resonator consists of four axially distributed high frequency ring current paths and a dielectric support, at least four high frequency current paths interconnect each pair of adjacent ring paths, at least one discrete capacitor is placed in each current loop but arranged so that none of the ring current paths is interrupted by a capacitor.
