dc.description.abstractHigh power millimeter wave and terahertz sources are used in DNP/NMR spectroscopy to greatly enhance the NMR signal. A key issue is the efficient coupling of the source power to the sample. We present HFSS calculations showing that the MIT 250 GHz DNP/NMR system provides a B[subscript 1] value of 13 μT/W[superscript 1/2]. The simulation shows the importance of the diffraction of radiation passing through the RF coil, leading to non-uniform illumination of the sample. A simple single pass model yields insight into the origin of the observed B[subscript 1] value. Methods of optimizing the B[subscript 1] value are described.en_US
