ABSTRACT:
A radio frequency volume resonator mounted on a 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 on the dielectric support. At least four high frequency current paths interconnect each pair of adjacent ring paths. The ring segments with interconnecting segments form loops. At least one discrete capacitor is placed in each loop.
