Tóm tắt

A Gordon-type coupler is described for a three-loop two-gap resonator for electron paramagnetic resonance (EPR) spectroscopy at 19 GHz. Dimensions and microwave characterization of the resonator also are provided. The resonator is particularly intended for aqueous samples in ‘‘flat cell’’ geometry. The range of coupling is sufficient to match flat cells of optimum thickness for best sensitivity. The coupling is based on overlap of evanescent fields of the loop gap resonator and transmission line.
