T. Atsumi et M. Miyagi, FABRICATION OF HIGHLY EFFICIENT POLARIZING ALUMINA FILM BY PULSED VOLTAGE ANODIC OXIDIZATION AT LOW-TEMPERATURE AND ITS APPLICATION TO BULKPOLARIZERS, Electronics & communications in Japan. Part 2, Electronics, 81(3), 1998, pp. 17-22
In order to form a polarizing alumina film by low-temperature anodizat
ion, the anodization voltage and concentration of sulfuric acid were o
ptimized. It was found that when pulsed anodization was used instead o
f a constant anodization voltage, the substrate was efficiently cooled
and the quality of the anodized film was improved. The polarizing alu
mina film was used as a bulk polarizer. (C) 1998 Scripta Technica, Ele
