研究目的
Investigating the transmission of the Gaussian beam from the gyrotron output window to the NMR system in the high-magnetic field regime.
研究成果
The rectangular corrugated waveguide shows similar characteristics to the circular one with wider bandwidth at higher frequencies. The back-to-back rectangular corrugated horn enhances the coupling coefficient of the non-ideal Gaussian beam to the fundamental HE11 mode, making the system efficient for terahertz transmission in DNP-NMR spectrometers.
研究不足
The study focuses on a specific frequency range (280?GHz to 450?GHz) and material (brass). The practical implementation and alignment of the system may pose challenges.
