<p>A sample cavity resonator for NMR spectroscopy contains a pair of diametrically opposed paraxial post structures (55, 55') approximating a single turn inductance about the axially positioned sample. The posts are separately excited in 180 degree relative phases by respective coupling loops (76, 76') spaced between the corresponding post and the cavity wall. A slideable piston structure (60) capacitively couples to the posts and provides cavity tuning.</p> |
