摘要

在基于平面基板的线栅偏振器中，如果填充因子(FF，金属条宽度与周期的比率)超过90%，则可以实现高消光比(~ 60 dB)和低插入损耗(几dB)。在本研究中，我们利用这些高FF线栅偏振器首次实现偏振w波段雷达。

New high-extinction wire-grid polarizers for polarimetrie W-band radar

In planar substrate-based wire grid polarizers, it has been found that high extinction ratio (∼60 dB) and low insertion loss (a few dB) can be achieved if the fill-factor (FF, ratio of metal strip width to period) exceeds 90%. In this research, we utilize these high FF wire-grid polarizers for a first implementation of polarimetric W-band radar.
