摘要
分析了测量布儒斯特角时出现折射波功率大于入射波功率的异常现象原因:在喇叭口面上折射波场的相位偏差小于入射波场的相位偏差,喇叭接收折射波的增益大于接收入射波增益。提出了改进方法。
The cause of an abnormal phenomenon that the refractive wave power is greater than the incident wave power when measuring the Brewster angle of dielectric is analyzed.The phase deviation of the refractive wave field is smaller than that of the incident wave field in the aperture of the horn.The gain of the horn for the refractive wave rises compared with that for the incident wave.The improving measures are proposed in the summary.
