摘要：
We present ideal terahertz linear polarizers made of a 1 mu m-thick freestanding carbon nanotube film consisting of highly-aligned multi-wall CNT sheets. The extinction ratio of our polarizer reaches similar to 30 dB from 0.1 to 2.0 THz. Since neither e-beam lithography nor chemical etching is needed, easy, quick and safe manufacture of the polarizer is possible.
