Cu and Ag were implanted into the pores of anodic alumina by means of electroplating. Its transmitted and polarized spectra was measured using UV-3101 spectral photometer,and the relationship of polarization property and incident angle was also studied. The experimental result indicated that such anodic alumina with metallic columns had good polarization property in the near-infrared waveband,and the incident angle had obviously effect on its polarization property.
