摘要： A saddle coil for multiple tuned response is realized by a segmented sequence of first LC elements each tuned to exhibit a low impedance at .omega..sub.1 and a second set of LC elements, each tuned to exhibit a low impedance at .omega..sub.2, at least some of said first set of LC elements having one of said second LC elements in parallel therewith.

摘要： A double-tuned dual port segmented coil for NMR studies of a volume distributed sample is obtained by coupling corresponding junctions of respective segments of two segmented loop portions with legs comprising L.sub.x C.sub.x L.sub.x series combination. Four segment coil portions so coupled support two isolated input ports across C.sub.x for adjacent such legs.
