Abstract
A dual resonator structure for a nuclear magnetic resonance probe includes an inner coil having a solenoid coil and an outer coil having a saddle coil. The inner coil is configured to tune a first channel to a first frequency and the outer coil is configured to tune X and Y channels to second and third frequencies independent from and simultaneously with the first frequency. The outer coil is radially spaced from the inner coil. The outer coil and the inner coil are configured to produce orthogonal magnetic fields.
