我们提出了一种在 94 GHz（W 频段）微波频率/附近工作的双模谐振器，并支持在样本位置具有相同场极化的两种微波模式。数值分析表明，两种模式的频率及其频率间隔都可以在高达 GHz 的宽广范围内调谐。谐振器被构造用于执行脉冲 ELDOR 实验，“泵浦”和“检测”频率的可变分离高达 Delta nu = 350 MHz。为了检查其性能，在代表性双自由基系统上进行了测试 ESE/PELDOR 实验。 (C) 2011 Elsevier Inc. 保留所有权利。
We present a dual-mode resonator operating at/near 94 GHz (W-band) microwave frequencies and supporting two microwave modes with the same field polarization at the sample position. Numerical analysis shows that the frequencies of both modes as well as their frequency separation can be tuned in a broad range up to GHz. The resonator was constructed to perform pulsed ELDOR experiments with a variable separation of "pump" and "detection" frequencies up to Delta nu = 350 MHz. To examine its performance, test ESE/PELDOR experiments were performed on a representative biradical system. (C) 2011 Elsevier Inc. All rights reserved.
