对植入金属柱的阳极氧化氧化铝的光损耗进行了理论评估。已经表明，布置在氧化铝膜中的微柱产生强烈依赖于偏振方向的光学损耗。在红外中，水平和垂直于列轴的两个偏振之间的损耗差异大于10dB/微米。因此，金属注入氧化铝有望成为一种具有大消光比和低插入损耗的高效偏振器。
A theoretical evaluation has been made of the optical loss of anodically oxidized alumina with implanted metallic columns. It has been shown that microcolumns arranged in the alumina film give rise to an optical loss that strongly depends on the direction of polarization. A loss difference between two polarizations, horizontal and vertical to the column axis, is larger than 10 dB/microm in the infrared. Therefore the metal implanted alumina is expected to be an efficient polarizer with large extinction ratio and low insertion loss.
