摘要

我们探索使用平行板谐振器的研究薄长方体样品在广泛的磁共振频率范围内。平行板谐振器的工作频率从几十兆赫到几百兆赫。提出并讨论了在8 ~ 500 MHz频率范围内的7个平行板谐振器。在含锂核和氢核的水平和垂直孔磁系统上进行了磁共振实验。平行板射频探头易于制造和优化。实验和仿真结果表明，平行板型射频探头具有良好的灵敏度，在较高频率下灵敏度下降较小。

The parallel-plate resonator: An RF probe for MR and MRI studies over a wide frequency range

We explore the use of the parallel-plate resonator for the study of thin cuboid samples over a wide range of magnetic resonance frequencies. The parallel-plate resonator functions at frequencies from tens to hundreds of MHz. Seven parallel-plate resonators are presented and discussed in a frequency range from 8 to 500 MHz. Magnetic resonance experiments were performed on both horizontal and vertical bore magnet systems with lithium and hydrogen nuclei. Parallel-plate radiofrequency (RF) probes are easy to build and easy to optimize. Experiments and simulations showed good sensitivity of the parallel-plate RF probe geometry with a small decrease in sensitivity at higher frequencies.
