Claim Text:
1. A nuclear magnetic resonance probe, comprising: a first radiofrequency coil patterned on a planar dielectric substrate, said first radiofrequency coil formed of conductive material, said first radiofrequency coil generating a first magnetic field that is resonant at a first radiofrequency; a second radiofrequency coil patterned on said dielectric substrate, said second radiofrequency coil formed of conductive material, said second radiofrequency coil generating a second magnetic field that is resonant at a second radiofrequency, said first radiofrequency coil and said second radiofrequency coil forming a first double-resonance apparatus; a second double-resonance apparatus positioned substantially parallel to said first double-resonance apparatus; and a sample region formed between said first double-resonance apparatus and said second double-resonance apparatus, said sample region configured to receive a nuclear magnetic resonance sample, said first magnetic field of said first radiofrequency coil being substantially parallel to a plane of said dielectric substrate in said sample region, said second magnetic field of said second radiofrequency coil being substantially perpendicular to said plane of said dielectric substrate in said sample region, said first radiofrequency coil being substantially in the shape of a figure-eight and patterned on a side of said dielectric substrate that is proximal to said nuclear magnetic resonance sample, said second radiofrequency coil being a spiral resonator and patterned on an opposite side of said dielectric substrate that is distal to said nuclear magnetic resonance sample, wherein said first magnetic field and said second magnetic field excite or detect respective nuclear magnetic resonance signals at said first radiofrequency and said second radiofrequency alternately or simultaneously wherein said second magnetic field is orthogonal to said first magnetic field at their respective resonant frequencies in said sample region.
