TL;DR: In this paper, it was shown that when the polarizer was illuminated slightly off axis, a degenerate mode was excited, which is resonant at the design center frequency, and was the cause of the problems.
Abstract: During development of a Venetian Blind polarizer, high reflections and substantial pattern deformation were noted. Analysis showed that when the polarizer was illuminated slightly off axis, a degenerate mode was excited. This mode is resonant at the design center frequency, and was the cause of the problems. A design developed using dual vanes has been shown to be free of the problem. It also has greater bandwidth.
