Abstract
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.
