摘要：

为了满足脉冲式电子顺磁共振谱仪的需要，设计并制作了连续波谐振腔和脉冲谐振腔. 连续波谐振腔采用矩形谐振腔的设计，而脉冲谐振腔采用了微型平面腔的设计. 在设计阶段，使用Ansoft-HFSS三维电磁仿真软件对2种谐振腔进行模拟计算. 微型平面腔的加工采用了微纳加工技术. 制作完成的谐振腔的参数指标由网络分析仪测定. 实验测得2种谐振腔的参数指标符合理论模拟值，并满足脉冲式电子顺磁共振谱仪的要求.

Abstract:

The continuous wave and pulse resonant cavities were designed and manufactured for the pulsed electron paramagnetic resonance (EPR) spectrometer. The resonant cavity used for the continuous wave EPR was a rectangular resonator, and the pulse resonant cavity adopted the structure of planar microresonator. The software of 3D electromagnetic simulation, Ansoft-HFSS, were used for simulation. The parameters of the designed resonators were evaluated with the network analyzer. The experimental data were found to be consistent with those of theoretical simulation.

Key words: electron paramagnetic resonance, rectangular resonator, planar microresonator
