Abstract :
By shining mm-waves upon a sample containing unpaired electron spins, DNP provides a way to enhance NMR signals. We report the characterization of a universal polarizer for EM-waves at 140 GHz made by rectangular grooved mirrors as well as design considerations for optimizing the coupling of a millimeter wave Gaussian beam to DNP/NMR samples.
