| 摘 要： | 本文提出一种利用四探针原理的微波极化干涉仪。四探针系统由两个T形波导分支和一个串连在其间的可调移相器替代。该干涉仪,特别适用于测量瞬变等离子体的参量,并具有同时显示等离子体的传输,反射和带极座标原点的极化特性的能力。在频率10GHz和35GHz下,用日光灯作瞬态放电实验的照片是清晰的。

| Abstract: | A microwave polar interferometer using four-probe principle is presented, in which four-probe system is replaced by two T-junction waveguides in series with a tunable phase shifter between them. The interferometer is specially suitable for measuring the parameters of plasma transient process, and has the capability of displaying transmission, reflection, and polar characteristic with the origin of its coordinates at the same time.The experimental photographs of a transient plasma in the daylight lamp are clear at frequencies of 10 GHz and 35GHz. |
