摘要:

将椭圆偏振测量法(椭偏法)的电磁频谱从原来可见光、红外波段拓展到毫米波段,对毫米波椭偏法测量原理进行理论分析,使用已构建的实验装置进行测量.通过对测量结果的分析,选择合适的入射角,经过大量测试,计算出被测介质材料的复介电常数.

关键词: 复介电常数;椭圆偏振测量法(椭偏法);反射系数;毫米波

Abstract:

 The electromagnetic frequency band of ellipsometry is extended from visible light and infrared band to millimeterwave band. We analyze the measurement principle of ellipsometry in millimeterwave band, and carry out experiments using a selfbuilt measurement apparatus. From the measured results, an appropriate incident angle is chosen. We obtain complex permittivity of materials based on a large amount of measured data.

Key words:  complex permittivity; ellipsometry; reflection coefficient; millimeterwave
