Abstract:
An rf LP saddle coil for use in nuclear magnetic resonance and characterized with respect to a Cartesian coordinate system having z and y axes, the coil comprising:a first semi-coil on the surface of a cylindrical coilform aligned with the z axis, said first semi-coil comprising a conductor pattern executing at least one loop around the positive y axis and having inductance L.sub.1,a second semi-coil on the opposite surface of said cylindrical coilform, said second semi-coil comprising a conductor pattern executing at least one loop around the negative y axis and having inductance approximately equal to L.sub.1,two conductive paralleling strips near the central transverse plane of said coilform providing parallel interconnection between terminations of said first and second semi-coils such that the parallel inductance L.sub.P is greater than L.sub.1 /2, and a center-feed rf line connected to said paralleling strips.
